A man goes to a bar and he says:

-Bartender, give me a whiskey quick or I'll do what my father did.

The bartender, scared, gives him the drink. The second day it happened the same. The bartender's curiosity was growing each time the man was coming in until he had to ask.

-Sir, if you don't mind, can you tell me what your father did?

-Oh yah, he went to another bar.
