Mordecai and Rigby: Ping pong! (They start playing with Muscle Man and Hi-Five Ghost) Hi-Five Ghost: I got it! (He hits it with his paddle) Muscle Man: Nice! (Mordecai hits it with his paddle, then Muscle Man hits it with his paddle, then Rigby hits it with his paddle) Mordecai: Oh, Rigby... (Muscle Man tries to hit it, but missed it) Muscle Man: Aw, come on! Rigby: You gotta go long with the ping pong! (The guys laugh) Mordecai, Rigby, Muscle Man and Hi Five Ghost: Ping pong! Ping pong! Ping pong! Ping Pong! (They laugh again) Muscle Man: Augh! What's your problem, bro? Dale: Muscle Man? Rigby: Really?
