Mystery Science Theater 3000, Season 7

[Shortly after finding a laser cannon in the desert, Billy begins hopping around oddly and pretending to blow stuff up.]

Billy:
Pow! Pa-pow!

Servo:
After all that, it's "pa-pa-pow".

Mike:
Once you're over the age of 11, you should not say "pow".

[Billy continues to prance about the desert with the laser cannon on his arm, moving rather daintily.]

Servo:
I think he's doing Frampton Comes Alive.

Mike:
...So, it's a thing that makes you waltz.

Crow:
Won't he be surprised to learn that it doesn't go "pow" but "fffwissshh"!
