Mr. B
He was just hilarious, running around with that napkin sticking out of his shirt, yelling "Hey, this is no playground!!! Wash cahhs, come on, wash cahhhss!!!!" He and his idiot son were both just too d*mm funny!!! Stereotypes, sure, but that's pretty much what this movie was, both comic and serious. Loved it as a kid and still do!!! I still remember the first time I saw it on TV in the late 70's, and thinking how much older and fatter Ivan Dixon looked than in "Hogan's Heroes"....
"COME ON, WASH CAHHHHS!!!!"
