Why are women like KFC?
After you've finished with the thigh and breasts, all you have left is a greasy box to put your bone in.

Explanation
Experiment
This is a crude and objectifying joke that compares women to a box of KFC. The setup implies that after using the 'thigh and breasts' (a sexual reference to a woman's body), the only thing left is a 'greasy box' (a reference to female genitalia) to put your 'bone' (a penis). It's meant to be shocking and vulgar.
