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.
Fan Dumb: People complained at Tatsu, who had been under the weather, about a glitched 4/6/13 update to YouTube which was due to a glitchy computer and then said people complained some more when the updates were delayed until Tatsu fixed his computer. Tatsu was enraged enough to consider not updating for a period of time.
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?
Never Live It Down: A minor example from the Super Mario World Spam Play with Khold, Khold was playing and he came across a bat enemy and he said "Oh hey, a Tatzubat" and Tatsu started raging.
Another example which he is trying to make GD Joel into this is the "Eat the Robot" quote from Insane Troll Logic.
Too Dumb to Live: Corn depending on the situation. He has been lost in Mercy Hospital in Left 4 Dead's No Mercy, caused multiple restarts in the Death Toll finale, and made terrible decisions in New Super Mario Bros. Wii that killed one or two of the others or the entire team (himself included).
What Do You Mean, It's Not for Kids?: The entire concept, which really didn't help with the Spam Plays of Kingdom Hearts, Goof Troop, Super Mario World that they did, which despite the kid-friendly games, the commentary is definitely not. Ex: The crew reading the in-game text with Corn using a deep-voiced black guy voice and saying "Touch any of my shit, I'ma go, I'ma stab you with my penis."
Tatsu's playthrough of Barney's Hide and Seek could count. Many people feel sorry for the kids that just wanted to watch an innocent gameplay video.
Also, Tatsu and Dergin's playthrough of Sesame Street: Once Upon A Monster, which still has the vulgar commentary you'd expect of Multipurpose Spam.
Some time back, a "soccer mom" tried to get Tatsu to tune down the vulgarity because her kids were watching. Tatsu proceeded to give An Aesop about how (paraphrased) "you shouldn't get all angry that your kids are watching me, when you're the one that should be controlling what they watch and not trying to get me to control the way I act."
