A daughter asks her dad if she can have a sleepover with her girlfriends and he agrees.
Later on, he over-hears their game of truth or dare to which the daughter's friend asks her when the last time she had an orgasm was.
The daughter replied, "Oh, about 3 days ago."
Her dad bursts into the room and screams, "I KNEW YOU WERE FAKING LAST NIGHT!"
