The assignment

A young female teacher is giving an assignment to her sixth-grade class. Because it is a lengthy assignment, she starts writing high up on the chalkboard. Suddenly, there is a giggle behing her. She quickly turns around and asks, "What's so funny, Patrick?"

"I just saw one of your garters," Patrick says,wide-eyed.

"Get out of my classroom!" she yells. "I don't want to see you for three days!"

Turning back to the chalkboard, she realizes she forgot to title the assignment and reaches to the very top of the board. Suddenly, there is an even luoder giggle. She spins around and asks, "What's so funy now, Billy?"

I just saw both of your garters," Billy says.

"Get out of my classroom," she yells again. "And I don't want to see you for three weeks!"

Embarrassed and flustered, the teacher drops the eraser. When she bends over to pick it up, there is a burts of laughter. She quickly turns to see Johnny leaving the classroom.

"Where do you think you're going?" she asks.

"Based on what I just saw," Johnny says, grinning from ear to ear, "my school days are over!"
