Texas or New York

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 girl from New York 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??
