A zombie walks into a bar and asks the bartender for a beer. Bartender says "We don't serve zombies in here" Zombie, a little pissed replies "Give me fucking beer", Bartender says "we don't serve angry, demanding zombies in here" The zombie is real pissed now, he retorts "If you don't give me a beer right now, I'm going to walk down to the end of the bar and eat that woman in the red dress right in front of everyone." Bartend says "We don't serve angry, demanding, threatening zombies in here". Now the zombie is really angry and true to his word he walks to the end of the bar, grabs the woman in the red dress and eats her. When he is done, he returns to the other end of the bar and says to the bartender "now, how about that beer?"
Bartender, as calm as can be, turns to the zombie and states "We don't serve drug users in here" The zombie, confused asks, "What does that mean?"
The Bartender replies "That was just a barbituate" (Bar-Bitch-You-Ate)
