They were:

Why Conan O'Brien and Jim Gaffigan? Well, the answer is relatively simple:
 * Michael Brandon
 * Alec Baldwin
 * Conan O'Brien
 * Jim Gaffigan
 * Eddie Redmayne
 * Greg Page
 * Murray Cook
 * and Joan Cusack


 * Conan guest starred as the voice of Santa Claus in the Backyardigans episode "The Action Elves Save Christmas Eve" and Jim Gaffigan starred in a 30-minute short featuring him as a pup on PAW Patrol to promote the second season of his own show, the Jim Gaffigan Show. Plus, Gaffigan's a relatively clean comedian, meaning he doesn't use bad words in his routines, which are generally about laziness, parenting, and eating. Aside from that, he has stated on stage that he's Christian (well, Catholic actually, but you get the point).
