DJ Butcher is the lead character in a television series that bears his name in "Roasted Guy".
As Peter and Brian watch, a club patron where DJ works approaches him, leading him to ask if he is picking up meat or picking out a song. When he offers a sample, the patron wants to know if he means a sample of the meat or a piece of song repurposed into another song, confusing him as he admits he probably should quit his job.
He returns in "Follow the Money," at a strip club.
