Rock, Paper, Scissors

Rock, Paper, Scissors is a game played in Regular Show by Mordecai and Rigby. (and Pops, as he says back in Lolliland that they play it by a different name) Mordecai and Rigby once played a bunch of times and caused a green monster to appear. In Race Against The TV, Mordecai and Rigby play it to see who has to ask Muscle Man for him and Five's TV. Mordecai loses, having rock and Rigby had paper.
