Little Johnny is squirming around at his desk, scratching his crotch and paying little attention to the English lesson going on in the classroom. When his teacher Mary goes over to find out what’s going on, Johnny is quite embarrassed. He whispers to Mary that he’s recently been circumcised and he’s gotten very itchy. So Mary tells him to use the phone in the corridor to ask his mother what he should do about his itch. Johnny does as he’s told and 5 minutes later returns to his desk.
Within minutes, there’s a commotion around his desk and when Mary goes to investigate, she finds Johnny sitting there with his penis hanging out his trousers.
"I thought I told you to call your Mother," she says to him.
"I did teacher," he replies. "She told me that if I could stick it out till lunch time, she'd come and pick me up from school."
