Perhaps you know popular Newgrounds animator Egoraptor and his hilarious YouTube friend with his own show, JonTron (if not, definitely take the time to educate yourself for endless laughs). If you don't know already, they started a channel called Game Grumps where they play games and talk over them. It's not even scripted so it makes for hilarious dialogue.
And for their mini-series, Game Grumps VS, where they play ridiculous games against each other.
They release around 1-3 videos a day, so it's something consistent to watch if you like them.
