A bear walks into a bar...

... and orders a beer. The bartender says "We can't serve a bear in this bar. State law."
Bear says "You had better serve me a beer, or I will kill and eat that woman at the end of the bar."
Bartender says "I told you. No beer for no bear in this bar."
Bear goes down to the end of the bar, kills the woman, and eats her. Places his bloody paw on the bar and asks "Now do I get that beer?"
Bartender says "I won't serve a beer to a bear in this bar. Particularly a bear on DRUGS!"
Bear says "What drugs? I'm clean!"
Bartender says "I saw that bar bitch you ate."
