@MrQ45 Here's the scene from "Car Wash" with a barely visible Danny DeVito, who argued with his wife or GF in the film.  The lady is the one who works at the diner next to the car wash, and who can be seen approaching the phone booth that T.C. eventually gets to to win the radio contest.  I remember seeing the scene on HBO as a kid, he gets into petty arguments throughout the film, and then storms out.  On the DVD, all you see is him storming out, with no reference as to who he is or why.
