The School Master

A Young school master rushed into the headmasters study in a distraught state,

"Oh Sir", he cried, "Ive just caught three small boys trying to see how high they could pee up the side of the classroom wall"

"And what did you do?" asked the headmaster calmly,

"What did I do, I hit the ceiling" said the teacher,

"Oh good shot" said the headmaster, "Thats one up for the staff"
