Game Grumps 

A let’s play YouTube channel staring Arin “Egoraptor” Hanson and Danny “Sexbang” Avidan. Their episodes often involving silly voices, jokes, running gags, making fun of games (typically Sonic the Hedgehog) and insightful advice and life stories. Also shows by the name of Steam Train, Grumpcade and Steam Rolled appear in the channel, although not as frequent, it is also expected for the channel to have various random segments every now and then.
