Two roaches were munching on garbage in an alley, when one engages in a discussion about a new restaurant in town.  "I was in that new restaurant across the street," said one.  "It's so clean the kitchen is spotless and the floors are gleaming white.  There's no dirt anywhere....it's so sanitary that the whole place shines!"  "Please," said the other roach, totally disgusted, "not while I'm eating!"
