Ok, here ya go.
A man was driving through rural Alabama one Saturday on his way back from Home Depot. As he passes a field he notices a country bumpkin out in the middle in a row boat. As he continues to look he notices the man actually rowing. So he pulls over, gets out, and yells at the man.
"Sir you are why peolpe think we are stupid in the south! If I could swim I would come kick your butt!"
