A teacher notices that a little boy at the back of the class is squirming
around, scratching his crotch, and not paying attention. She goes back to find
out what's up. He's quite embarrassed and whispers that he has just recently
been circumcised and he's quite itchy.
The teacher has him go down to the principal's office, to phone his mom, and
ask her what he should do about it.
He does this and returns to the class, sits down in his seat and suddenly,
there's a general commotion at the back of the room.
Back down she goes, only to find him sitting at his desk with his penis
hanging out. "I thought I told you to call your mom," she says.
"I did," he says�, and she told me that if I could stick it out till noon,
she'd come and pick me up from school�.
