Renaeden's airplane joke reminded me of this one:
A woman from Texas and another from New York were seated side by side on an airplane. The woman from Texas, being friendly and all, said: “So, where are you from?†The New York woman said, “From a place where they know better than to use a preposition at the end of a sentence.†The woman from Texas sat quietly for a few moments and then replied: “So, where are you from, bitch?â€
