stupid joke

A warning to all you - be careful about drink driving as we are getting close to Christmas. The Police are out there in numbers checking on people. Last night I was out for a few drinks. One thing led to another and I had a few too many beers. Not a good idea. Knowing I was over the limit, I decided to leave my car where it was and took a bus home. Sure enough, I passed a Police control where they were pulling over drivers and performing breathalyser tests. Because I was in a bus they just waved it past. I arrived home safely and without incident, which was a real surprise as I've never driven a bus before and I am not even sure where I got it from...
