Mr. Prusko is such a boring teacher that students can't even stay awake in class, so Lex and Presley make a deal to make him cooler in exchange for good grades, but Mr. Prusko becomes too cool and is now known as Mr. P.

Presley, Lex and Munchy are excited when they buy a karaoke machine from the "Karaoke Kickoff" show; when the machine breaks, the kids head to the studio to get their money back.
