A bad day
A little guy is sitting at the bar staring at his drink when a large, threateningly leering biker steps up next to him, grabs his drink and gulps it down in one swig.
"Well, watcha' gonna do about it?" he says menacingly, as the little guy bursts into tears.
"Come on, man," the biker says, " I didn't think you'd cry. I can't stand to see a man crying."
"This is the worst day of my life," says the little guy.
"I am a complete failure. I was late to a meeting, and my Boss fired me. When I went to the parking lot, I found my car stolen and I don't have any insurance, I left my wallet in the cab I took home. I found my wife in bed with the gardener and then my dog bit me.
"So I came to this bar to work up the courage to put an end to it all.
"I buy a drink, I drop a capsule in, and sit here watching the poison dissolve. Then a wise-ass like you shows up and drinks the whole thing!"
