A young couple had a wild Saturday night and used two condoms
from a new box of twelve.

The following weekend the woman discovered that there were only
six condoms remaining in the box.

"What happened to the other four condoms?" she asked.

His nervous reply was, "Er, I masturbated with them."

Later, she approached her male confidant friend, told him the
story, and then asked him, "Have you ever done that?"

"Yeah, once or twice," he told her.

"You mean you've actually masturbated with a condom before?" she
asked.

"Oh," he said, "I thought you were asking if I'd ever lied to my
girlfriend."
