The Mercy of River Song vs. Police Squad!'s "Freeze" Frames
It's a woman who scares even space-Nazis vs. the cancelled embryo of Naked Gun spoofing the hell out of one of TV's cheesiest tropes!
The Mercy of River Song
Police Squad!'s "Freeze" Frames
The case for The Mercy of River Song
Introduced as a sometime companion of the Doctor who he keeps meeting in anachronic order, River Song is deliberately enigmatic during her first few seasons on the show - partly to avoid creating a paradox with her future knowledge of the Doctor's life, mostly because it amuses her to see him flustered. The only concrete fact about her is that she's an incredibly dangerous person to be on the wrong side of, as best seen when she faces off against a Dalek. For clarity, Daleks are the show's equivalent of Nazis, terrifying even to the Doctor - they're genocidal cyborgs whose response to most lifeforms is to try to exterminate them. River, however, inspires a slightly different reaction.
The case for Police Squad!'s "Freeze" Frames
Before Top Secret!; before Angie Tribeca (but after Airplane!) there was 1982's Police Squad!, Zucker, Zucker, & Abrams' short-lived master class in cop-show parody.* We have PS! to blame for spawning the Naked Gun movies . . . but a show that did this with epilogue freeze frames should be forgiven everything. *Bonus points for being decades ahead of the curve in deep-sixing the laugh track
