I say, let’s give ’em one! I’m not going to do them all, but just to start off the conversation:
102- THE ROBOT VS. THE AZTEC MUMMY–A snippet of the silly Aztec ceremony and the singing lady.
104- WOMEN OF THE PREHISTORIC PLANET–“Hi-keeba!”
106- THE CRAWLING HAND–“No dancing. Not allowed.”
107- ROBOT MONSTER–“I cannot! But I must!”
108- THE SLIME PEOPLE–The Tom Waits guy in the theater.
110- ROBOT HOLOCAUST–“Yoo and yur dawtah ah doomt!”
111- MOON ZERO TWO–The girl walks into the locker room and gets a good look at our hero.
201- ROCKETSHIP X-M–“Mars, extending us a welcome!”
204- CATALINA CAPER–A shot of Little Richard, looking high on goofballs
806- THE UNDEAD–“STAAAAY!”

Some of them are obvious. But maybe you have a better choice? Let’s hear it! (And any KTMA fans who want to suggest stingers for them are welcome.)
