Gutbusters

Gutbusters is a game that Grandpa Heffley has in Diary of a Wimpy Kid Rodrick Rules. The game is where one player reads a card, and the others try not to laugh. Greg Heffley always beats Grandpa Heffley. At one point at the end of the second book, Rodrick Heffley stole his journal and tried to make it into the bathroom. He would have made it in there is someone hadn't left the game sitting out.
