"No beer for a bear in Big Bill Burger Bar" joke

I came across this joke whilst listing to our local radio station!
There was a bear that had been walking for a very long time and decided to call in to the local bar, Well he goes into the bar, sits himself down and says to the bar tender "I would like a beer thanks"
The bartender replies "Sorry mate we do not sell beer to bears in Big Bill Burger Bar"
Now at this point the bear is getting angery so he thumps the bar and repeats "I would like a beer"
Once again the Barman replies " Sorry mate we do not sell beer to bears that bang on the bar at Big Bills Burger Bar!"
Now by this time the bear is getting pretty angery and starts to bash to costomers that was sitting next to him!
And the bear says again "I would like a beer please"
And once again the barman replies "sorry we do not sell beer to bears that bash the bar and bistanders!"
Now by this time the bear was anger than hell so the bear picks up some empty bottles and starts to throw them at the barman.
The bear repeats "I would like a beer please"
The barman replies "sorry we do not sell beer to bears that bash the bar and the bistanders and also thow bottles around the bar at Big Bills Burger Bar"
Well that did it for the Bear, so the bear gets up off of the seat opens his mouth and takes a chunk out of the bar!
"Now give me my blasted beer!"
The Barman replies with "Sorry we do not give beer to bears that bash the bar and bistanders and also throw bottles around the bar and that are also on drugs!"
The bear replies with "what do you mean DRUGS??? I admit to Bashing the bar and the bistanders and throwing the bottles, but what is this about me being on drugs!"
And the barman replies with "Well what about the Bar-Bit-You-ate!!
If you are not sure if you get that joke read it again and say Bar-Bit-You-Ate fast and then see if you get it or not!
