A group of 3rd, 4th, and 5th graders, went on field trip to see a brand new racetrack in their community. The idea was the children could learn about thoroughbred horses and actually get to see some of the horses in their stalls. The children were accompanied by two female teachers.
After walking around the race track for a couple hours it was time to take the children to the bathroom. Since there were only two teachers it was decided that the girls would go with one teacher and the boys would go with the other. The teacher assigned to the boys waited outside the men's room. All of a sudden one of the boys came out and told her that none of them could reach the urinals - they were all to high.
Feeling awkward but having no choice, the teacher had to go inside to help each one of the boys. First she undid their pants, then she hoisted them up up one by one. It was obvious she was going to have to hold their "you know what" to direct the flow away from their clothes. As she lifted the fourth boy the teacher could not help but notice that this boy was unusually well endowed for his age.
Trying not to show her embarrassment she said, "You must be in the 5th grade." “No, ma'am”, he replied, “I'm riding “Silver Arrow” in the seventh race today, but I really do appreciate your help”
