A girl from Texas and a girl from New York are seated side by side on an airplane. The girl from Texas, being friendly and all, asks, "So where y'all from?" The girl from New York says, "from a place where they know better than to use a preposition at the end of a sentence." The girl from Texas sits quietly for a few moments and then replies, "So where y'all from, bitch?"
ETA: you ladies are awesome! 1) I'm not from TX but I saw the joke and thought I would share and 2) It went from a joke to a grammar post I Love it!! :)
