These viral campaigns have become very common. Putting a celebrity into a video makes it highly visited, but if you record him(her) with doing something incredible, PUM! We have a viral video.
In the next video with Evan Longoria, seems like the man had the senses of Spider-Man. The video is sponsored by Gillette (see the advertising at the far end).
And in the next video with David Beckham, we see that advertising is much more direct, sponsored by Pepsi.
Maybe many people believed those videos were real, but if Beckham could get 3 balls at that distance in 3 different trash cans in a row, why he would not score goals as easy in the field?
