Naruto and Shino go on a mission together to Motoyoshi Village where a man named Fuuta has a strange request. When his father died he put in his will that at his funeral, if Fuuta were to laugh, the inheritance money would be split amoung the family. The relatives would be willing to do anything to make him laugh so he asks Konoha to put in a replacement for him. Shino was perfect for the job but the food was drugged with laughing potion and he started cracking up. So, now Naruto must sit through the entire funeral without laughing at all.
