There's this guy in a bar, just looking at his drink.
He stays like that for half-an-hour.
Then, this big trouble-making truck driver steps next to him, takes the drink from the guy, and just drinks it down.
The poor man starts crying. The truck driver says: "Come on man, I was just joking. Here, I'll buy you another drink. I just can't stand to see a man crying."
"No, it's not that. This day is the worst of my life. First, I fall asleep, and I go in late to my office. My boss, outraged, fires me. When I leave the building, to my car, I found out it was stolen. The police say they can do nothing. I get a cab to return home, and when I leave it, I remember after he drives off that I left my wallet and credit cards there. The cab driver just drives away. I go home, and when I get there, I find my wife in bed with the gardener. I leave home, and come to this bar. And when I was thinking about putting an end to my life, you show up and drink my poison."
