The boys go to the men's room and discover they can't reach the urinals and report this back to the teachers, both female. One decides she'll help them up so they can reach. One by one they enter and the teacher notices one is particularly well endowed. She ask him how old he is and in which class he is in. He replies "Not in any class ma'am, I'm riding Whistlestop in the fifth race, but thanks for the help".
