The american dub version of the Bomber-Nanimon/Citramon episode, and that's all I'm gonna say.
Digimon Savers has one that's a callback to Adventure, or rather the first movie: Koromon's first action upon hatching is to latch onto Masaru's head!
Marcus in the dub of the semifinal episode: "King Drasil is a PC?!" Probably not meant to be funny, but it caused a lot of "Digimon runs on Windows" jokes.
