When: 2004, Super Bowl XXXVIII, New England Patriots (W) vs. Carolina Panthers (L)
Who: Janet Jackson, Justin Timberlake, P. Diddy, Nelly, Kid Rock in an American flag poncho
Boom: Jackson's infamous "wardrobe malfunction," which just happened to show off her super-sweet nip jewelry (see 6:06). Nelly was too far away to loan her a Band-Aid, but perhaps the boob was a boon. A month on, JJ's Damita Jo popped out onto the charts at a pert No. 2.
Bust: Don't make us say it. You're better than that. Really.
