Here at my local BWW, they use a bhut sauce, and the bhut powder for their wing challenge...
In order to win, you have to eat them faster than the previous record (57 seconds for my local one). If you win, you get your picture taken, and the wings are free.
but who wants to eat 10 wings in under a minute, then sit there for the rest of the meal watching the rest of the party eat? lol
