That would be soooooooooooooo funny. You know what would be even funnier? If Samsung or one of the other worldwide sponsors pulls out of their sponsorship. That would be funny. Because then, the athletes who currently compete for free, would have to finance their own trip. All would not be lost though. They could get an easy $4-500 for that iPhone.
You are right, there wouldn't be an Olympic without these sponsors. Thanks god for these sponsors. I wonder who was the sponsors of the earlier games, maybe the athletes sell apples on the street corners too?
