A Goon's Deed in a Weary World - S7-E11
Trivia: Kenneth and Jack compare giving a tour of the station to Willy Wonka. Later as Kenneth and track are actually giving the tour we see the guests, which all match characters from Charlie and the Chocolate Factory. One is overweight and has a German accent like Augustus Gloop, one woman is wearing a red dress reminiscent of Veruca Salt, one is wearing a bolo tie like Mike TeeVee, one is very similar to Violet Beauregard. And finally one is seemingly pure of heart and clean cut like Charlie Bucket.
