This spot featuring Roger Federer, Thierry Henry and Tiger Woods premiered in early 2008. Federer went from averaging double digit titles a year before the campaign, to totaling eight wins in the two years since. Henry has become a global goat for his handball. And know.

David Beckham's contract with Gillette ran through 2007, the year he became the world's only superstar athlete who managed to fade into obscurity by playing in Los Angeles. Was this year's MLS Cup disappointment a direct result of his association with Gillette? It's tough to be certain, but yes. Yes it was.

This ad featuring Sergio Garcia premiered in the summer of 2008, right after El Nino won The Players Championship. He's 0 for 27 on the PGA Tour since.

Oh, and that other guy in the spot, Ricky Rubio? He had the misfortune of being taken by the Timberwolves, and scurried back to Spain.

The curse doesn't stop at "real" sports. John Cena signed a deal to become a Gillette pitchman in February of 2008, just after winning the Royal Rumble as a surprise entrant. But as we all know, he managed to lose three straight title matches in the next three months.

So how about Derek Jeter? The man's superhuman. Gillette ads, SI's Sportsman of The Year, and no divine retribution. If he manages to get himself on the cover of Madden 11, the universe may collapse in on itself.
