A Duck Walks Into a Wine Bar

A Duck Walks Into a Wine Bar and jumps up onto a stool at the bar. The bartender comes over and asks what he wants.
The duck says "i'll have a beer thanks"
The bartender says that we don't sell beer here it's a wine bar. "What else do you want?"
Again the duck says "i'll have a beer thanks"
Now the bartender is getting a little annoyed, and says again "this is a wine bar and we don't sell beer. So what else is it then"
The duck says "i'll have a beer thanks"
Now the bartender is getting mad, he leans towards the duck and says "now duck this is a wine bar and we don't sell beer, if you ask for a beer one more time i'll nail your beak to the bar, so what will it be?
duck says "got any nails"
