The Grumps (formerly known as Game Grumps) is a variety content YouTube channel founded and originally hosted by Jon and his friend, Arin Hanson, better known as Egoraptor. The channel was originally dedicated to Let's Play content where Jon and Arin would play various games and banter with one another. Around the time Season 2 of JonTron premiered, Jon revealed that he had left Game Grumps to focus on his own content. He was replaced by singer Dan "Danny Sexbang" Avidan of the musical duo Ninja Sex Party. Eventually the channel was rebranded as simply "The Grumps" and the content was changed to a more variety style, focusing on different shows, beyond just gaming.
The show is notable for spawning Jon's characteristic "Ech!" catchphrase.
