A substitute teacher walks into the classroom on the blackboard she sees
a message.

It says, "Jimmy Poole, has got the biggest tool, in the whole
damn school!"

She yells, "Whose Jimmy Poole?"

This kid in the back
stands up and says, "I'm Jimmy Poole."

"Well, Jimmy, your staying after
school!

The very next day when the substitute teacher walks in, she
looks up at the blackboard and written on it, it says, "PAYS to
ADVERTISE."
