Cop 1: Well, look at this. Power windows, power seats. I bet you the thing cost 6 grand.
Agent J: Ah, yes, and it has a roof, but it's hidden.
Cop 2: Hey, what kind of work do you do? An individual of your... Particular ethic persuasion?
Agent J: Mmm...
Cop 1: Maybe he's a noted athlete.
Agent J: Mmmm! Yes. Starting forward for the Detroit Darkies.
Cop 1: Where'd you get the car?
Cop 2: And the suit?

As the hand creature busts the shackles off Boris' legs in Lunar Max, you can see the bottoms of his pants over his metal prison boots. There are only a few folds and wrinkles over his left foot, and the pants over right foot are hardly wrinkled at all, or affected as the creature climbs up his right leg. But only a couple of seconds later, we see another shot of Boris' feet as the creature breaks off the metal sleeve of his arm, and suddenly his pants legs are very wrinkled. Boris was standing perfectly still the entire time. Boris' legs are also suddenly closer together.
Even though Frank the pug doesn't appear, there are a couple of references to him. The first one is a big picture of him over J's bed and when J gets pulled over by the cops, there is a billboard advertising for "The Amazing Talking Pug."
