I've entered a Billy Mays costume photo contest being run by his son, Billy Mays III.  Rule #2 of the contest - "Be tasteful (zombies are allowed)".  
If I had given myself more time to rehearse I was tempted to send in a video instead of a photo.  Since I decided on the costume so many months ago, I've been cultivating my impression and I think I'm pretty damn good at it at this point.
