Certainly the best song sung by Steve Martin playing a sadistic biker-dentist in a musical horror movie about a cannibalistic plant based on a stage musical derived from a Roger Corman film, ever.

From Frank Oz’s Little Shop Of Horrors (1986), with music and lyrics by Alan Menken and Howard Ashman. Martin is a gleeful, malicious riot. Trigger warning to those with dentist phobias…which includes me, but I laughed anyway.
