This is one of my favorite scenes from the original Car Wash movie with Richard Pryor.  Oh yeah there is cursing in this clip so if that offends you, do not read more.

 

There is a saying that "There ain't nothing new under the sun" and that is the truth.  However the Pointer Sisters singing in this clip is beyond I mean woo.  Richard Pryor also was an excellent comedic actor.  Let me also say Bill Dukes was a genius.
