A bear walks into a bar...

He bruskly orders a beer.

Barkeep blares, "We don't serve beers to bears in Biloxi."

Bear replies, "Barkeep, please; just a beer..."

"We don't. Serve beers. To bears. In Biloxi."

Bear bends in, motions barkeep to do the same, "You see that woman at the end of the bar? If you don't give me a beer, I'll kill her and eat her up."

Barkeep looks a bit bewildered, but replies, "You do what you gotta do. We don't serve beers to bears in Biloxi."
Bear stands up, kills and eats the woman. He returns to the barkeep.

Before the bear can say anything the barkeep raises a hand and says, "... And we don't serve drug addicts either."

It's the bear's turn to look bewildered, "What do you mean drug addict?"

Barkeep looks bemused, "We don't serve beers to bears in Biloxi and that," motioning to what remained of the woman, "was a bar-bitch-you-ate."
