A fellow picks a woman up in a bar and takes her home.

When he takes off his shoes and socks, it is apparent that his toes have had something dreadful happen to them.. "Eeek!" says she. "Oh, I used to have toe-lio," says he. "You mean polio?" "No, toe-lio." So they continue.

When he takes off his pants, his knees look like they have been beaten with sledge hammers. "Eeek!" says she. "Oh, I used to have the knee-sles," says he. "You mean measles?" "No, knee-sles." Still undaunted, they continue.

When he takes off his underpants, she laughs and says, "Don't tell me! Small-cocks!"
