Some cool/funny sports commercials:

Nike Freestyle Soccer (These are all real moves... no computer generated images!)

Nike Secret Tournament ( Awesome action, awesome music and three minutes long... this one is da bomb! More about it here and here .)

Ali G stumps Kobe Bryant (Respect!)

Here is a collection of some really good Nike commercials on iFilm.com (I don't know anything about iFilm but it came up when I Googled "Nike commercial". Sometimes it's finicky and won't load after you hit "watch" so you have to close the window and hit "watch" a second time. Although I haven't looked at them I'm pretty sure they're all "G" rated since they're TV commercials. Enjoy! )

Check out this Nike commercial called "Move" which was shown during the 2002 Winter Olympics (in Park City) ... I think this is the 30-second version, but there was an unprecedented 90-second version that won an Emmy award. I don't watch much TV, but during the Olympics I always had it on and when I'd hear the music to that commercial (or if my kids heard it they'd call: "Papa, the commercial is on!") I'd stop to watch it... I can't really explain it but the music and the images just do something for me... I'd be curious to read your comments on it...
