The name of the band, Mordecai and the Rigbys, was made up by Rigby. Originally, the band was going to be called "Mustache Cash Stash", a suggestion by Mordecai. Other suggestions for a band name were "Cool Dudes", "Face Punch", "Rad & Subtract", "Helicopter Crash", and then finally "Mustache Cash Stash".
- If one looks very closely in Bet to Be Blonde or Bad Kiss, they can see the Mordecai and the Rigby T-Shirts in Mordecai and Rigby's closet.
- In real life, stores like Hot Topic sell Mordecai and the Rigbys t-shirts.
- The name Face Punch that Rigby suggested is a spoof of the band name Fist Pump from Caffeinated Concert Tickets.
