There was this guy at a bar, just looking at his drink. He stays like that for half of an hour.
Then, this big trouble-making truck driver steps next to him, takes the drink from the guy, and just drinks it all 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 grown man cry."
The man shakes his head. "No, it's not that. This day is the worst of my life. First, I over-sleep, and I'm late to my office. My boss fires me for it. When I leave the building, to go my car, I found out it was stolen. I get a cab to return home, and when I leave it, I discover I lost my wallet and all of my credit cards along with it. The cab driver just drives away, calling me fowl names. When I walk into my house, I find my wife in bed with my best friend. I leave home, and come to this bar. And just when I was thinking about putting an end to my life, you show up and drink my poison."
