A guy went into a bar, sat down at the bar and ordered a beer. The bartender handed him a draft beer and left it in front of the guy. The bartender then returned to the other end of the bar.
The guy drank half the beer and poured the other half on his left hand. The bartender saw this and just shook his head. The guy asked for another beer. The bartender handed him another and resisted the temptation to ask the guy what he was doing. Once again, the guy drank half the beer and poured the other half on his left hand.
The bartender has seen a lot of strange behavior from drunk people, but this guy was sober! The guy asked for another beer. The bartender handed him another and found that he couldn't resist asking, 'Buddy, I can't help noticing what you're doing. What's going on?' The guy looked at him and said, 'What does look like? My date and I are having a drink!'
