EX. The Game Grumps is my new favorite internet show. You get to watch a let's play of a classic game, from Link to the Past to mother frickin' Goof Troop, and listen to two hilarious guys giving commentary and being silly. The hosts, Egoraptor and Jon Tron, were already two of my favorite people on the youtubes and their chemistry is awesome. Click one of the links bellow and enjoy the grumping.
