You ever hear the one about the paradox?
Well, a guy walks into a soda parlor, sits down at the counter and orders a Coke Float. He overhears two guys talking about a brain surgery they just finished. He looks at the counter clerk and says, “Man, those guys sure do sound smart. Brain surgery! What a feat.”

The guy then exclaims, “that’s a paradox!”
The clerk then says, “Naw, man, they’re just blue-collar guys.
