Speak Spanish??

A Texan is walking through a field and sees a Mexican drinking water from a stock tank, with one of his hands.

The Texan shouts to the Mexican... "Hey don't drink that water...It has cow shit in it!"
The Mexican shouts back ...

"Soy Mexicano, yo no entiendo inglés. Hábleme Español."
(I'm Mexican, I don't speak English. Speak Spanish to me!)

The Texan shouts back...

"Utilice ambas manos, usted conseguirá más para beber."
(Use both hands; you'll get more to drink)
