Most people try to avoid looking foolish, but when those people attend a show and there is a chance for some kind of prize, that prime directive goes right out the window. Vendors around the floor hand out shiny, blinking baubles that act as an entry in a contest.

The catch? The only way to win a prize is if you wear the silly vendor-specific bauble as you walk around the show floor--if the vendors select you from among the many be-baubled masses you, too, could finally be a winner. This is why you'll see many people at Macworld Expo 2009 wearing rabbit ears, such as the pictured author. If I wore those rabbit ears to an Apple Store I won't get jack squat beyond an odd look from the Genius Bar.

Only at Expo!
