1 mistake in Kimmy and the Trolley Problem!
Starring: Carol Kane, Jane Krakowski, Ellie Kemper, Tituss Burgess
Trivia: Star Ellie Kemper was actually a student of guest star Jon Hamm's acting class when she was in High School. They both found it very amusing that Hamm would go from being her old teacher to portraying a creepy perverted cult-leader who kept Kimmy held hostage.
