(Bryce Hodgson) stands on the bar and shouts "Are we having fun yet?", which was a catchphrase from the show Party Down (2009) - which was about caterers, similar to what Don E. is doing in this episode. Also, Ken Marino - who plays the lawyer Brandt Stone - starred in Party Down (2009).
Adam Kaufman (Harry Thorne) also appeared in a Veronica Mars (2004) episode, The Girl Next Door (2004). Rob Thomas created both iZombie and Veronica Mars.
