Times are tough.  Competition in the workforce is fierce.  Mere adequate performance doesn't cut it anymore.  If you can't find a way to make a difference for your employer, a metaphoric clone of you will step into one-half of a stationary camera shot and make you look bad.

Well, at least that's what happened in the mail room of a large company, where two identical twins turn the day-to-day administration of packages into a veritable Dead Ringers of shipping and handling.

Grease up your hair, put on one of many sport coats from the wardrobe department that don't quite fit right, and listen to the story of Walter, ne'er do well of the company, who puts his own manicure schedule, crossword addiction, and general bad 'tude ahead of all else.  You'll be glad you did.  That way, when you find yourself face-to-face with your own doppelganger, you'll have a competitive edge when it comes time for year-end employee evaluations.

Also, kill it with a shovel.  This isn't in the short, but your doppelganger is from a parallel universe, and is evil.  They all are.  You should know this without me saying so.
