There were two old geezers living in the backwoods of the Ozarks: Rufus and Clarence.
They lived on opposite sides of the river and they hated each other. Every morning, just after sunup, Rufus and Clarence would go down to their respective sides of the river and yell at each other.
"Rufus!" Clarence would shout, "You better thank your lucky stars that I can't swim, er I'd swim this river and whup you!"
