Drinking Game: Servo suggests drinking every time the annoying sidekick says Cabot's name. According to IMDB the name is said fifty-five times throughout the entire movie, mostly by the sidekick.
End of an Age: This was the final episode to feature invention exchanges. In the "Amazing Colossal Episode Guide" book, it's stated that the reason is that Mike isn't an inventor by trade like Joel was. So it didn't make sense for him to keep being somebody he's not.
Getting Crap Past the Radar: The lyrics to Tubular Boobular Joy as seen in the Quotes page - though it's not past the radar, it's in front of the radar showing off its naughty bits.
Say My Name: An absurd case; not only does useless little Watney repeatedly call out for Cabot, but the instant he returns to the city, everyone runs around shouting his name (a total of 19 times in about 90 seconds). It really starts to wear on the guys after a while.
Marlenus: Cabot! CABOT! Cabot... Servo: So, Cabot, then. [...] Marlenus: Cabot! It is Cabot; he has returned, my darling! CABOT! Mike: "Oh, it's a different Cabot." [...] Marlenus: CABOTTTT! Talena: Cabot? Crow: So, uh, Cabot's coming, then? Servo: Yeah, pretty much. (All three, in agreement, repeat "Cabot" for a while) Mike: Personally, I think Cabot is highly overrated, but... eh. Talena: CAAAAAABOT! Servo:(Getting annoyed) So our hero's name is WHAT, again? Mike:(Sagely) Cabot.
Squick: Invoked by Mike and the bots, who have this reaction when Cabot and Talena make out.
Throw It In: In-universe, a few jokes are made of Jack Palance supposedly going off-script, like when he accuses the queen of acting like a "bitch in heat."
Title Confusion: The title Outlaw was only used for this episode. It was released elsewhere as either Outlaw of Gor or Gor II. Servo understandably thinks at first it's the film starring Jane Russell, especially since Howard Hughes heavily promoted Russell's breasts. (George S. Kaufman stated, "They ought to call it 'A Sale of Two Titties'".)
Visual Pun: Mike's pose for Inherit the Wind makes it look like he's farting.
Wham Line: In-Universe. Mike and the bots find an autobiography with journal excerpts on Jack Palance's experiences making this movie. They're having fun reading about Jack's drunkenness and the general lack of care on set when they get to an entry that reads "I think I killed a man. More later". They conclude that it's time to put down the book for a while... note Until they realize there is an entire chapter dedicated to Tango & Cash.
