A little girl and a little boy are taking a bath together when the little girl looks down and asks, "What's that?" The little boy says, "That's my little red race car." 10 minutes later, the boy looks down and asks, "What's that?" The little girl says, "That's my little red race car garage."
So later that night the boy asks the little girl if he can put his little red race car in her little red race car garage. She says yes, and they pull down their pants and the boy tries putting his little red race car in her garage, but it won't fit. Downstairs, the mother hears an ear-piercing scream and runs upstairs, flips on the lights, and sees blood on the floor. The mother asks, "What happened?" The little girl says, "We tried putting his car in my garage and it wouldn't fit, so I cut the back wheels off."
