FUnniest Prank in an 日本动漫 you've ever seen

Mine:
From: Toradora
Prank: Takasu is inspecting the upstairs of Kawashimas 海滩 house Villa, he accidentally discovers the bathroom and walks in, Ami was in the 淋浴 but Not the way she made it sound, she had been cleaning the 淋浴 but pulled Takasus leg 由 making it sound like he walked in on her, he had gotten out after being mocked and taunted 由 Ami, he complained to Taiga (Ignored in the Manga, Yelled at yet understood in the Anime) In the 日本动漫 Taiga walks upstairs after yelling at Takasu when he failed the inspection of the upstairs, 由 THAT time Ami was ACTUALLY in the bath and Taiga got a slap for walking in, she was totally jealous of Amis Boob size so she got a Wash tub to the back of the head for THAT...
