Only two of the contestants in this episode, AJ Michalka ("The Goldbergs") and Nolan Gould ("Modern Family"), currently has a TV gig. Some of the others a list that includes Bronson Pinchot, Tom Arnold, Dave Coulier, Tracey Gold, Joey Lawrence, Corbin Bleu, Lisa Whelchel and Kim Fields haven't been seen in years.
