My favorite Slim Whitman reference comes from Weird Al's "The Biggest Ball Of Twine In Minnesota":
We picked up a guy holding a sign that said, "Twine ball or bust"
He smelled real bad and he said his name was Bernie
I put in a Slim Whitman tape, my wife put on a brand new hair net
Kids were in the back seat jumping up and down Yelling, "Are we there yet?"
