The Janitor's Boy is a children's book by Andrew Clements.

Part of his school series, it was released by Simon & Schuster in 2000.

Jack is made fun of by his friends for this, and he hates his father because of it.

Lashing out, he puts a massive quantity of bubble gum up under his desk so that his father will have to clean it off.

As the book closes, a student shouts "You gonna be a janitor when you grow up too?!"
