Bubba Ray and Lonnie rent a boat and go fishing.
They catch a lot of fish and return to the shore.
Bubba Ray says to the Lonnie, "I hope you marked the spot where we caught all those fish." Lonnie replies, "Yes, I marked an 'X' on the side of the boat to mark the spot." Bubba Ray says to Lonnie sharply, "You idiot. How do you know we'll get the same boat?"
