Angry Joe has published a couple of interviews with the dev team of The Witcher 2: Assassins of Kings Enhanced Edition. Learn more about the game and see what Joe was doing in Warsaw.
The videos can be found here.
He gets quite agitated and curses like a sailor when he reviews a bad game... (Fable 3 comes to mind, some film-based videogames like Thor and the Green Lantern games also come to mind, but there are worse examples [like 1 score or smthg] which I havent seen). Capcom seems to be his favourite punching bag...
But he liked The witcher 2, and he loves CDProjekt apparently, so he's just happy and goofy here.
You wanna see Joe angry? You won't like him when he's angry. At the top of my head I suggest you view the movie licensed games as someone already suggested (Thor, Iron Man 2, Green Lantern). He also throws a bit of a fit on Mass Effect 3, despite the high score. Sonic Free Riders is also good, but my personal favorite Joe tantrum has to be on the Mindjack review.
