Speaking German in Texas

Rico says his friend Bob Leone sends along this one:

In Texas there is a town called New Braunfels, where there is a large German-speaking population.
One day, a local rancher driving down a country road noticed a man using his hand to drink water from the rancher's stock pond.
The rancher rolled down the window and shouted: Sehr angenehm! Trink das Wasser nicht. Die kühe haben darein geschiessen. Which means: Glad to meet you! Don't drink the water. The cows have shit in it."
The man shouted back: I'm from New York and just down here campaigning for Obama. I can't understand you. Please speak in English.
The rancher replied: Use both hands.
