This little short guy is sitting at the bar just staring at his drink. He's been sitting there for half an hour when this big trouble-making truck driver steps next to him, grabs his drink and gulps it down in one swig.
The poor little guy starts crying.
"Come on man, I was just giving you a hard time." says the truck driver.
I'll buy you another drink. I just can't stand to see a man crying."
"This is the worst day of my life." says the little guy between sobs.
"I can't do anything right. I overslept and was late to an important meeting, so my boss fired me. When I went to the parking lot, I found my car was stolen and I have no insurance. I grabbed a cab home but, after the cab left, I discovered I had forgotten my wallet in it.
At home I found my wife in bed with the gardener. So I came to this bar and was thinking about putting an end to my life, and you show up and drank the damn poison."
