With Jerome Horwitz holding its Invention Convention, George Beard and Harold Hutchins are forced by Mr. Krupp to stay in study hall all day due to them glueing everyone to their seats the previous year.

The convention soon has to be called off, and Melvin breaks his promise on purpose and tattles after Krupp is left confused.

With each boy using a quick line-writing device, they write all their lines in three-and-a-half minutes, then makes a Underpants comic.

The trio slings chipped beef with his underwear, and the Toilets vomit all the teachers out and die.

He fears that he will be fired for the damages, but the Robo-Plunger repairs all of it, and flies off to Uranus with the command never to return.
