Role in episode
Gary reads this book while trying to avoid getting bath water splashed on him by SpongeBob. He flies to the chair in SpongeBob's living room and begins reading this book while SpongeBob continued to chase him, making puns like "Come back, Gary! I have something to chair with you!" SpongeBob probably made all these puns up, as he saw Gary was reading a joke book.
