S1·E15 Battle of the Bands

After coming across a bunch of musical instruments in the audio booth, the gang decides to start a band. Unfortunately, they are really bad. When Ozu listens however, he mistakes Mikey's cell phone ring tone for their music and turns "LilyMu" into an act to take advantage of their musical prowess. They go along with the lie for a bit until a group of girl rockers call them out. Then it's time for a Battle of the Bands.
