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. 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 pored 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!"
