....as relayed by my brother. I'm not sure if this is true, but this is what
he said:

I was driving to work the other day when I tapped the rear end of a car
that had stopped in front of me. I got out to survey the scratch on this
guy's bumper. So did the other guy.

When he stepped out of his car, I saw he was a DWARF! He walked to
the back of his car, put his hands on his hips, and said "I AM NOT HAPPY".

Then I said "Well, which one ARE you?"

That's how the fight started.
