There was a Mississippi redneck and a Louisiana Cajun, fishing on their respective sides of the Mississippi river.
Just as soon as the redneck put his line in the water, he slung a fish onto the bank, and the Cajun was catching nothing, so he yelled across to the redneck, "Buddy, I'd sure like to be on your side of the river!"
"Aight, tell ya whut, I'll shine my flashlight 'cross this river, and you can walk across this little beam of light!" the redneck yelled back.
The Cajun replied, "Hain't no way, buddy. I know you think I'm a fool! When I get halfway 'cross, you'll turn your flashlight off!"
