Young Gamers

The Young Gamers are two kids appearing in the episode "High Score". They seem to very experienced at Broken Bonez. They got 700,000 until Mordecai and Rigby (and G.B.F.) beat their high score at it. Also, they appear not to care about anyone as they run into Mordecai and Rigby and "nearly kill them" with their skateboards but after Mordecai and Rigby defeat them in Broken Bonez, they then respect Mordecai and Rigby.
