Regular Show Easter Egg - Konami Code in Regular Show

In the episode where Rigby "mysteriously" beat Skips in arm-wrestling, it showed one scene where Mordecai and Rigby were playing an 8-bit version of Guitar Hero. After watching Mordecai play a successful string of notes, Rigby tries for himself. However, Rigby ends up messing it up, and he gets bottles thrown at him.

Mordecai shouts "Dodge the Bottles, Dodge the Bottles! Up, Up, Down, Down, Left, Right, Left, Right!"

This is the first part of the Konami Code (excluding the "B, A, Start!" at the end.)
