a ladder top having a plane having a periphery with a hook receiver which engages with the hook in the object so the object is held securely to the ladder top, the hook receiver is a tab hole so when the extension tab of the paint cup is inserted into the tab hole, the paint cup is securely held to the ladder top, the extension tab has a vertical portion that is inserted into and extends down from the tab hole in the ladder top, and a horizontal portion which extends from the tab hole out over the periphery of the ladder top from the tab hole so the paint cup clears the side of the ladder top, but is held security in place to the ladder top, the ladder top having a first side, a second side, a third side and a fourth side, all of which extend down from the plane, the first side opposing the second side with the plane therebetween, the third side opposing the fourth side with the plane therebetween, the third side and fourth side connected to the first and second side, the hook receiver adjacent the second side, the cup having a perimeter wall having an opening with a cross-section less than half of the top's length, the handle having a horizontal portion that extends outward from the perimeter's side, the handle having a vertical portion extending perpendicularly downward from the horizontal portion so the vertical and horizontal portions together forming an L shape, the extension tab extending outward from the perimeter wall and in opposition with the handle;

a front section having a first front rail attached to the ladder top and a second front rail attached to the ladder top and rungs attached to the first front rail and to the second front rail; and

a rear section having a first rear rail attached to the ladder top and a second rear rail attached to the ladder top and rungs attached to the first rear rail and to the second rear rail, the rear section and a front section able to pivot about the top and relative to each other to move between a use state where the front section and rear section form an angular relationship apart from each other, and a closed state where the front section and rear section are essentially in parallel with each other, the second side of the ladder top disposed over the rear section, the paint cup being over the rear section of the ladder.

2. A method of holding securely an object to a stepladder comprising the steps of:

aligning an extension tab, dove tab or T-tab of an object, the object being a one-piece paint cup having a handle, over a tab hole, dove slot or T-slot, respectively, of a ladder top of the stepladder, the ladder top having a plane having a periphery with the tab hole, dove slot or T-slot which engages with the extension tab, dove tab or T-tab in the object so the object is held securely to the ladder top, the ladder top having a first side, a second side, a third side and a fourth side, all of which extend down from the plane, the first side opposing the second side with the plane therebetween, the third side opposing the fourth side with the plane therebetween, the third side and fourth side connected to the first and second side, the tab hole, dove slot or T-slot adjacent the second side, the stepladder having a front section and a rear section, the second side of the ladder top disposed over the rear section, the cup having a perimeter wall having an opening with a cross-section less than half of the top's length, the handle having a horizontal portion that extends outward from the perimeter's side, the handle having a vertical portion extending perpendicularly downward from the horizontal portion so the vertical and horizontal portions together forming an L shape, the extension tab, dove tab or T-tab extending outward from the perimeter wall and in opposition with the handle; and

moving the extension tab, dove tab or T-tab relative to the tab hole, dove slot or T-slot, respectively, so the extension tab, dove tab or T-tab engages with the tab hole, dove slot or T-slot, respectively, so the object is held securely to the ladder top, the paint cup being over the rear section of the ladder.

3. A stepladder system comprising:

an object having a hook, the object having the hook being a one-piece paint cup having a handle, and a dove tab; and

a stepladder comprising:

a ladder top having a plane having a periphery with a hook receiver which engages with the hook in the object so the object is held securely to the ladder top, the hook receiver is a dove slot, the shape of the dove tab conforms with the shape of the dove slot so that when the dove tab is inserted into the dove slot, the paint cup is security held to the ladder top, the shape of the dove tab is such that it has a narrower width closest to the point that it extends from the paint cup and is wider in width at the front of the dove tab, the dove slot has a corresponding shape where the width of the dove tab is wider along the face of the side of the ladder top that has the dove slot and is narrower in width at the rear of the dove slot so that the dove tab basically hooks with the dove slot, the cross-section of the dove slot forms a partial V, with the shape of the dove slot also forms a partial V, the ladder top having a first side, a second side, a third side and a fourth side, all of which extend down from the plane, the first side opposing the second side with the plane therebetween, the third side opposing the fourth side with the plane therebetween, the third side and fourth side connected to the first and second side, the hook receiver adjacent the second side, the cup having a perimeter wall having an opening with a cross-section less than half of the top's length, the handle having a horizontal portion that extends outward from the perimeter's side, the handle having a vertical portion extending perpendicularly downward from the horizontal portion so the vertical and horizontal portions together forming an L shape, the hook extending outward from the perimeter wall and in opposition with the handle;

a front section having a first front rail attached to the ladder top and a second front rail attached to the ladder top and rungs attached to the first front rail and to the second front rail; and

a rear section having a first rear rail attached to the ladder top and a second rear rail attached to the ladder top and rungs attached to the first rear rail and to the second rear rail, the rear section and a front section able to pivot about the top and relative to each other to move between a use state where the front section and rear section form an angular relationship apart from each other, and a closed state where the front section and rear section are essentially in parallel with each other, the second side of the ladder top disposed over the rear section, the paint cup being over the rear section of the ladder.

4. A stepladder system comprising:

an object having a hook, the object having the hook being a one-piece paint cup having a handle, and a T-tab; and

a stepladder comprising:

a ladder top having a plane having a periphery with a hook receiver which engages with the hook in the object so the object is held securely to the ladder top, the hook receiver is a T-slot, the T-tabs extend from the paint cup and engage with the T-slot in the ladder top to securely hold the paint cup to the ladder top, the T-slot essentially has a cross-section of a T, with a horizontal portion disposed in the plane of the ladder top, and a vertical portion disposed in the side of the ladder top and connected with the horizontal portion to form the T, the T-tab has a cross-section of a T with a vertical portion that extends through and down from the horizontal portion of the T-slot in the ladder top, the T-tab also has a horizontal portion that extends from the paint cup to the vertical portion of the T-tab which rests on and fits into the side of the ladder top having the T-slot and fits into the vertical portion of the T-slot, the ladder top having a first side, a second side, a third side and a fourth side, all of which extend down from the plane, the first side opposing the second side with the plane therebetween, the third side opposing the fourth side with the plane therebetween, the third side and fourth side connected to the first and second side, the hook receiver adjacent the second side, the cup having a perimeter wall having an opening with a cross-section less than half of the top's length, the handle having a horizontal portion that extends outward from the perimeter's side, the handle having a vertical portion extending perpendicularly downward from the horizontal portion so the vertical and horizontal portions together forming an L shape, the T-tab extending outward from the perimeter wall and in opposition with the handle;

a front section having a first front rail attached to the ladder top and a second front rail attached to the ladder top and rungs attached to the first front rail and to the second front rail; and

a rear section having a first rear rail attached to the ladder top and a second rear rail attached to the ladder top and rungs attached to the first rear rail and to the second rear rail, the rear section and a front section able to pivot about the top and relative to each other to move between a use state where the front section and rear section form an angular relationship apart from each other, and a closed state where the front section and rear section are essentially in parallel with each other, the second side of the ladder top disposed over the rear section, the paint cup being over the rear section of the ladder.
