Late for Work Excuses - Real & Imaginary

On Friday, I had to call my boss from the train station to let him know I'd be late for work because my train had not yet arrived.

I remember another morning when our area was hit by a supposedly hundred year flood, with water pouring down from the basement windows and up from the sewers. I say supposedly because the following year a similar flood occurred. Anyway, that made me late for work.

Maybe you'd like to share your experiences. What real or imaginary excuses have you used to explain being late for work? Or, what happend to one of your book characters on the way to work?
