While away at a convention, an executive happened to meet a young woman who was pretty and intelligent.  When he persuaded her to disrobe in his hotel room, he found out she had a superb body as well.  After petting and carressing her, unfortunately, the executive found himself unable to perform.

On his first night home, the executive walked from the shower into the bedroom to find his wife covered in a rumpled bathrobe, her hair curled, her face creamed, munching candy loudly while she flipped through a movie magazine.

Then, without warning, he felt the onset of a magnificent erection.  Looking down at this, he snarled, "Why you ungrateful, mixed-up son of a bitch.  Now I know why they call you a prick..!!"
