Silver Mini-Brain is the second song used by Mordecai and Rigby in the street performing competition. It was featured in the episode Silver Dude.
The song was made to ridicule Silver Dude for not being able to produce his own music.
We were the first ones singin' on the streets!
But then this Silver Dude shows up stealin' our beats!
It wasn't cool, it was a pile a stink
All he did was press 'Record' and didn't even have to think!
Not that he could, his head's really small
Dude's so dumb that he doesn't have a brain at all!
Oooooooohhh, Silver Mini-Brain!
