These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Freudian Trio: Arguably, Corn is the Id (does a lot of his stuff in most games, particularly the Left 4 Dead games, for the lulz of it), Tatsu is most likely the Superego (albeit with a terrible temper) and Spazzy is the Ego (although that's more out of process of elimination).
Hilarious in Hindsight: Tatsu tells Corn at one point in the New Super Mario Bros. Wii Spam Play that there wouldn't be another Luigi's Mansion game 'Because YOU play him!'...guess what was announced at E3?
Too Dumb to Live: Corn, depending on the situation. Forced the entire team to backtrack through a level in the first No Mercy playthrough, just to go rescue him with one health after he kept getting lost in the game, even with Tatsu and Spazzy giving him instructions, caused a majority of the restarts in the Death Toll finale by shooting his teammates but not the zombies, and made some terrible decisions in New Super Mario Bros Wii. After a game over caused by Corn, Tatsu used the Hilarious in Hindsight line.
