Here is a little joke passed to me by my brother-in-law.

I would like to share with you about drinking and driving.
As you well know, some of us have been known to have had brushes with the authorities on our way home from social ocassions over the years.
A couple of nights ago, I was out for a few drinks with some friends at the club hotel and had a few too many of a rather nice drink .
Knowing full well I may have been slightly over the limit, I did something I've never done before: I took a bus home.
Sure enough I passed a police road block but as it was a bus, they waved it past.
I arrived home safely without incident which was a real surprise, as I have never driven a bus before and am not sure where I got it.
