His John Madden impression in the Shenmue review has to be seen to be believed.
His constant jokes on the oddly named martial arts move "Pit Blow", culminating in:
"Is Ryo Hazuki gonna have to Pit Blow a bitch?"
"So they cast a comedian as the lead role for a game from a franchise that, even at the time, was known for laughably bad voice acting... I just thought I'd bring this up now, so you can understand why, whenever time the game tries to have a serious moment, I just imagine the lead character doing this." *cut to Patrick Harlan riding a quad and performing tricks*
Also from the same review, his rage-filled rant on the game's numerous plotholes. Made even funnier when he pauses halfway through to compose himself, only to be interrupted by his own voice-over who continues ranting in his place.
When zombie Santa Claus appeared in Zombie Panic in Wonderland. Followed by the drama-llama hitting the wall.
A rather unique Glitch in Red Steel occurred accidentally after passing a certain checkpoint, where the main character bent his left arm over his shoulder, bodies start hitting the floor through the ceiling, and... to simply put: Total Chaos followed by freaking out from SCR, an audio track, and the Wii itself.
In the same review, Mr. Game Player made a remark about fighting a Power Ranger. Then the theme song plays...
Followed by Seppuku with the Wii-mote after that revelation.
How part five of the Shenmue video ended with Mr. Game Player discovering that something actually happens in the game, followed by gleefully running out of the house.
The Stinger in War Gods where a deranged fan calls out SCR for not liking the game in question, followed by SCR being hilariously dismissive. This is followed by the fan telling a story that seems like it'd enter into Squick territory.
Mocking the One-Woman Wail in Evergrace and promptly imagining what the recording session must've been like.
A minor Hilarious in Hindsight moment: SCR returns a plastic cup to WellUnreal007 at Connecticon 2011. The same plastic cup that he left in SCR's car back at Anime North 2011.
The "Mac wants the flamethrower" clip from the Thing was used a few times.
Subverted and lampshaded in SCR's review of Cold Fear, where he slaps the joke with a newspaper.
"Bad overused joke!"
His attempts at playing Dance Dance Revolution on PS1 with the dance mat, with his hands! He... didn't last too long.
His video on the 4th of July had him reenact the civil war, with an inflatable Screamer model being the confederates. He reenacts by emulating Kenshiro, punching the crap out of it.
