Snail Jokes is a joke book that only appears in the episode Gary Takes a Bath.
The book's cover is dark green and the title is yellow.
Gary was reading this book while avoiding getting bathwater splashed on him from SpongeBob. He fled to the chair in SpongeBob's living room and began 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. The "snail on a ship" joke in "Dumped" that SpongeBob told Larry was one of Gary's favorites, so it probably came from this book, as it is a joke book about snails.
