Jenny kisses Brad on the cheek.
Crowd: (screaming)It's Armagedroid!
Kilgore: What? Hey, scream at me in fear for I am Kilgore!
Crowd: Hey, look it's the cute, little, harmless Kilgore. Awww!
Kilgore: No, fear me! Fear meeee!
This is the first time we see all of the space bikers without wearing their spiked helmets.
This is the first appearence of Kilgore since the episode Kilgore and the first appearence of Armagedroid since the episode Armagedroid.
When Jenny finds a panel appearing to read Vejur inside Armaggedroid, this is a reference to the V'ger probe from the first Star Trek movie, which had a similar panel attached to it (it originally read Voyager 6, but was obscured).
The way in which a second mouth comes out of Tammy's mouth is similar to the way an alien does it in the movie Alien, the Eighth Passenger.
