The one from the adidas ClimaCool advert where there's a Lance Bass looking dude in an orange shirt in the air at the end. Not the Anna K one, the other one.
I LOVE ANNA KOURNIKOVA for reals. Me and her, are going to get married. We aren't. We are just going to keep it secret.
The Lance Bass-looking dude is Australian swimmer Ian Thorpe. This link will show you the commercial and tell you its credits (but not the song info): http://www.boardsmag.com/screeningroom/commercials/267/ From a google search for «adidas climacool "tv commercial"», though (like the 10th or 15th one I tried), someone asked that question on another site and got an answer. It's "Look Who's Perfect Now" by Transister, on their 1997 self-titled (and only) CD. Some relevant GeoCities sites: http://www.geocities.com/transistermusic/ -- MP3s (get 'em before the bandwidth caps kick in!) http://www.geocities.com/transisternl/ -- lyrics, etc. {edited to show more cool stuff from boardsmag.com -- videos for "Fell In Love With A Girl" (in LegoVision) and "Video Computer System" (in 2600Vision)}
