something else funny

A girl from Texas and a girl from the east coast were seated side by side on an airplane. The girl from Texas, being friendly and all, said, "So, where ya'll from?"

The east coast 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 ya'll from, bitch?"

It didn't make me laugh, but I like it for a set of reasons including the issue of grammar, the use of geographical stereotypes, and the surprise.
