In the Donkey Kong Country 2 LP, during his run of the level Klobber Karnage, due to the emulator he was using (ZSNES) caused an emulation glitch that made the barrels spinning without stopping, when normally you could control those ones with no problem, which made the things 10x harder than really is... and he beat the unwinnable level, with some help, of course.
Nintendo Capri Sun has not played Battletoads before the 4-player race with Proton Jon, Super Jeenius, and Pcul. And yet he is actually placing third and doing respectably well, even having FUN in Rat Race.
Very notable in the fact that he says he's never PLAYED Battletoads.
Even more notably, he almost beat Rat Race... WITHOUT knowing that you could actually hit the rat in order to slow it down, which is what Pcull and Proton Jon did to beat the level.
In his Ocarina of Time Let's Play, he mentioned having done the WaterTemple without using the Zora Tunic the first time he played. While it's possible to do without the Zora Tunic, it's much easier with it.
He has beaten Contrawith one life. Not to mention, he plays the game like he does it every morning. What makes it more awesome? The next time he plans to beat the game, his special guest? His Mom. Manly.
Also some of his Self Imposed Challenges can go here. Did a Three-Heart Run of Zelda 2, beaten Super Ghouls n Ghosts, and did Legend of Zelda 1's Second Quest without the sword. He is crazy.
The Super Mario Galaxy 2 Part 47 video under Ensemble Darkhorse was so much so that it was the first of NCS's videos to reach 1 million views.
In his LMAO of Mario Party 2, he ends up dominating Mystery Land with a whopping 8 Stars, 4 times the amount of all the other players combined (Wario and Luigi had ONE Star each, while Donkey Kong got none), and swept all the Bonus Stars.
