The Mystery Science Theater 3000 presentation of The Indestructible Man has examples of:
Donut Mess with a Cop: Utilized so many times that in the final host segment, Joel, Servo and Crow agreed to sign an affidavit swearing that they would not make any more cop/donut jokes again.
Also done in real life by the Brains.
Not So Stoic: Another one of the few instances where Joel becomes angry and impatient. It occurs during a very long and very boring dinner date between a stripper and the detective.
Repeat After Me: When Joel reads the affidavit to not use any more cop & donut jokes:
Joel: I, state your name... Tom/Crow: I, state your name... (giggle) Joel: (irritated) Oh you guys, cut that out! That's just as bad as doing donut jokes!
The Mystery Science Theater 3000 presentation of Undersea Kingdom has examples of:
Call-Back: "Hurry, Diana!", as heard in future experiments. Or, more specifically, "DOOOOOYYYYYYYYYYAAAAAAAAAAAANNNNN!"
Left Hanging: Not only do they not view the next chapter of the serial, they don't even make it to the end of this chapter; halfway through the film just abruptly cuts off in mid-scene and the end card appears, and Servo delivers a quiet and sarcastic "Well, how about that?"
