The lead protagonist in this episode, Harry Gordon, has the same name as the show's set decorator.
Edna: You're a boob, Harry.
Gordon: I didn't come home to get called names.
Hobson: You think the syndicate's bringing in a new inside man?
Ness: If they are, someone's out of a job.
Edna: (to Gordon) He bought you with a nickel soda.
Narrator: (about Gordon) He followed Joey's progress like a printer...a printer printing his obituary.
Rico: (to Ness and Hobson) What are we...the good guys or the bad guys?
Tully: Joey, you're a genius!
Guido: Don't pin a medal on him 'til we see the beer.
Narrator: Harry Gordon was the king. The king of nothing at all.
This episode is the only one of the series besides the pilot that is based on a real life case of the Untouchables. The Capone Mob built a brewery on the top floor of a building and Ness and his Untouchables knocked it over.
