"I'm not happy"

On the way to the office this morning, I rear-ended a car.
Somehow I knew it was going to be a bad day.
The driver got out of the other car, and he was a dwarf, poor b*gger.
He looked at his dented car and then looked up at me and said "I'm not
happy"
I said, "Well, which one are you then?"
That's how the fight started.

Well as long as you didn't leave the scene feeling grumpy
