Mordecai and the Rigbys

Two-man (well, one blue jay, one raccoon), two guitar band featured in the eponymous episode of Regular Show. They have shirts before they learn songs. Thanks to a spilled soda and a gramophone-based time machine, they learn to rock from their future selves, who are successful musicians and (according to the closed captions) speak "British." But then they find that their future selves are just lip-synchers. Mordecai breaks up the band, keeping his integrity while losing the girl. Rock be a cruel mistress, my bird friend.

Other names considered during the band's formation: Cool Dudes, Face Punch, Ren's Trek, Helicopter Crash, and Mustache Cash Stash. We agree with Mordecai--should have used the last one.
