I remember there was one where someone says the wrong show and Ross just SCREAMS, *_"STEAM TRAIN!!!"_* at the top of his lungs, and then immediately with the most seething rage I've ever heard in anyone says *_"The NAME of the SHOW is S T E E E E E E E E A M ! ! ! T R A A A A A I N ! ! !"_* I can't remember when it was though, and I'm so upset I can't remember! That was a great moment!
You missed the one in the Leisure Suit Larry 6 playthrough where Dan starts saying Game Grumps, Barry edits in the top of the Grump endscreen banner poking in, but it pokes back out when Ross screams Steam Train. It was really funny (but other than that, good comp!)
