A group of primary school children are enjoying a day at the races. Due to staff shortages, only one female teacher is in charge on the trip. She splits the boys and girls into two groups for a toilet break and accompanies the girls into the facilities where everything goes smoothly. The boys however complain that the urinals are too high for them in the gents and they cannot use them so she has to go in with them. The only solution seems to be to hold each child and raise them to the right level. Worried that the unusual position might cause them to wet their trousers she even lightly supports their willies while they do what they need to. As she supports the last one she notices that he is a little 'large' for his age. She asks 'Are you from year 4"? "No", he replies. "I'm riding Silver Birch in the 2.30"!
