"Hamstringing" is a word in ENGLISH

A guy stumbles through the front door of a bar, ambles up to the bartender and orders a beer. The bartender looks at the drunk man and says,"I'm sorry sir, but I can't serve you...you've already had too much to drink." The guy swears and walks out of the bar. Five minutes later the guy comes flying through the side door of the bar, and yells for a beer. Again the bartender says,"I'm sorry, sir...but I can't serve you...you've already had too much to drink!" Ten minutes later, the same guy comes barrel-assing through the back door of the bar, storms up to the bartender, and demands a beer. Again, the bartender says to the man..."I'm really sorry, sir, but you've had too much to drink...you're going to have to leave!" The guy looks quizzically at the bartender and says finally, "My God, man... How many bars do you work at?!!!"
