Bad joke du jour

A girl from Texas and a girl from New York were seated side by side on an airplane. The girl from Texas, being friendly and all, said: "So, where y'all from?"
The New York girl said, "From a place where they know better than to use a preposition at the end of a sentence."

The girl from Texas sat quietly for a few moments and then replied: "So, where y'all from, bitch?"
