The formula for hosting your bros when they visit is pretty simple. It involves booze, and meat, and more booze, and more meat, and also more booze. The formula for when your grandparents visit, though? Or your sister with a kid? Not so much. As such, we've put together this handy step-by-step to tour-guiding Dallas for your less-than-ultimate guests: THE GUEST: YOUR SISTER AND HER THREE-YEAR-OLD KID You can only have Thomas the Tank Engine playing on your 60in 3DTV for so long before you realize, "Wait, why the f*** was George Carlin voicing a kids' show?", and also, "It might be time to leave the house."

When he gets tired, lunch at Lark on the Park beckons.
