A young couple had just had great sex. When they were finished, she looked in the box of condoms, but there were only six left out of twelve, so she asked him, "What happened to the other five condoms?"
His nervous reply was, "Er, I masturbated with them."
Later, she then approached one of her Male friends, told him the story, and then asked him, "Have you ever done that?"
"Yeah, once or twice," he said.
"You mean you've actually wanked with a condom before?" she asked.
"Oh," he said, "I thought you were asking if I'd ever lied to my girlfriend."
