In El Super Policia 880, a down-on-his-luck cop meets some aliens, who turn him into a super-cop. Soon he's stopping criminals, preventing professors from being zapped with their own super-weapons, and teaching all the other cops to dance.
It all culminates in this fantastic scene, where the aliens bring the cop and his son aboard their mothership — only to reveal their true hideous faces. Cue zany chase-around-the-space-ship scene, with plinky plonky jazz music. Note: Clip is in Spanish with no subtitles.
