Wow ~ it can get into a pretty extensive story...uhm, excuse!
"Attention Earthling Control Unit Boss,
We have found Susan to be a suitable specimen for our study of the inferior human race. This will require Susan to be late to work today. While planning the ultimate destruction of your puny and insignificant planet, Susan was captured and beamed to our testing chamber in a tank where we observed Susan doing the jitterbug while blindfolded. After intense probing, Susan was put in a plasma induction radiation chamber with a tennis racket, a stinky leopard and President Bush. Our findings revealed Susan likes eating raw gold fish while listening to Pink Floyd. Very disturbing, indeed. Other than now being very frightened by kitchen tongs, we return Susan in satisfactory condition. We have erased your employee's memory unit so do not mention any of this when Susan beams into work late today.

All this for a cup of Seattle's Best??
This is great! McDonald's offers an excuse generator that you can utilize to give yourself a few extra minutes in the morning to swing by and get a cup of coffee on the way to work. I prefer the alien abduction excuse, myself! 
You are saving the company money by not having to give you sick-pay!!!
