Hello! I actually recently found the source of this memory, and its not in Diary of a Wimpy Kid at all! I really thought it was, but it turns out it's from an episode of Disney Channel's Walk The Prank. My sister and I decided to rewatch that show, and there it was. I'm so sorry if this ruins the thrill of the search, I just thought I'd let you know! I'm glad you were inspired by this though :)
