Regular Show Saison 8 Épisode 24

Two bored groundskeepers, Mordecai (a six-foot-tall blue jay) and Rigby (a hyperactive raccoon) are best friends who spend their days trying to entertain themselves by any means necessary, much to the displeasure of their boss. Their everyday pursuits often lead to things spiraling out of control and into the surreal.

After a high school lab experiment goes horribly wrong, Mordecai and Rigby must go back in time to battle an evil volleyball coach in order to save the universe — and their friendship.
