- The Danza: Cecil, voiced by Cecil Baldwin, Kevin, voiced by Kevin Free, and Lauren, voiced by Lauren Sharpe. As noted below, they all have ties to the Neo-Futurists improv group which uses cast members' real names in sketches, likely the inspiration for the podcast."It was very strange for me, I think it was in the fourth or fifth episode, when I read the script and found out the characters name is Cecilwhich, of course, is my name," Baldwin said. "And I wrote Joseph an email and I was like, So am I playing myself or is this supposed to be autobiographical or am I playing a character who just happens to be called Cecil or is it just a coincidence or is it kind of all three together? And Joseph was like, Yeah, its really everything." —from an interview
