Writer's Block: Red-faced and ruddy

[Error: unknown template qotd]
The day I was travelling for work with a colleague and we got stuck on the motorway  for 4 hours because of a closed junction.  There was no hard shoulder because of a contraflow and I got so desperate I had to climb into the back of the car and try to pee in a plastic bag that I found ... which then split, meaning I had peed all over the back of my colleague's company car.

He nearly peed himself through laughing, and the news was all around the office before I'd brewed my coffee the following morning!!!
