The Big Sleep

Here is a funny news story read on an American media website:

A police officer was caught sleeping on the job in his car by an amateur video camera. Chief officer Christopher Deasy stated that: "The police officer was just a little run-down".  I think we would all be if we had to work double shifts and then start off duty work.

But how about you readers? Have you ever fallen asleep at work? Any good story you could share?
