A mans been drinking in the bar alone for three hours straight, and the bartender is getting worried about him. Hes downing whiskey sour after whiskey sour.

Finally, after the man orders his twelfth whiskey sour, the bartender shakes his head and says, Sir, I think youve had enough.

The drunk looks at the bartender closely and says, Wha – whas that you shay?

The bartender swallows.

I said, I think youve had enough sir.

The drunk points a finger….

Lis – l-l-listen Jack, I been drrrrrinking for shirty-thix years and I have no idea when Ive had enough… so h-how the h-hell should y-y-you?
