The grandfather in Boondocks was ok. The best was when he was talking back to Mike Ditka in his Viagra commercials. “Get back in the game? What game? What are you talking about? Football?”
Hmmm, I do sem to recall one strip where he tells the hateful little POS and his brother:
"Why don't you two little negros just go do a drive-by on each other and get it over with?"
Leaving them speechless.
