Alcohol
A guy walks into a bar and orders six shooters.
The bartender says, "Looks like you are having a bad day."
The guy says, "Am I ever!
I woke up late for work.
On my way to work, I got in an accident.
When I got to work, I was four hours late, so the boss fired me.
To top it off, I came home to my wife screwing my best friend."
The bartender says, "What did you say to your wife?"
The guy says, "I told her to get out, and I never want to see her again."
The bartender says, "What did you say to your best friend?"
The guy says, "BAD DOG!"
