What happened last time?
Monty pretended he hadn't bought the book because his bike had a flat tire, then rushed outside, destroyed his bike, and rushed upstairs to read the book. But then, Fireball catches him with the Prune-Proovingit book.
Fireball: Yes, it is pretty sweet.
Monty: That book is SO awesome!
Gumball comes in the room
Gumball: Why is the book Monty DIDN'T buy on his nightstand?
Monty & Fireball: AAAAH!
Gumball: Hey, Darwin, you gotta come see this! Monty got the latest Prune-Proovingit book!
Darwin: Hold on, let me get Daisy!
Meanwhile in Daisy's room
Darwin: rushes in DAISY! YOU GOTTA SEE THIS! YOUR BROTHER MONTY HAS THE LATEST PRUNE-PROOVINGIT BOOK!
Darwin and Daisy come in
Monty: WHAT? YOU INVITED DARWIN AND DAISY TO SEE?
