Keep your hands off my drink...
 

A little guy is sitting at the bar just staring at his drink 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 my wallet was still in the cab. At home I found my wife in bed with the neighbor. So I came to this bar trying to work up the courage to put an end to my life. And then you show up and drink the poison." :banana
