No. 19: Whitney Houston's amazing national anthem, Super Bowl XXV

It doesn't get any better than Whitney Houston's fantastic national anthem as the Gulf War was going on in 1991.

No. 16: Scott Norwood, wide right

With the Giants leading 20-19, the Bills take over deep in their own territory with 2:16 remaining. Jim Kelly marches the ball downfield and gets to the Giants' 29 with eight seconds left, setting up Scott Norwood for a game-winning 47-yard field goal. But he misses.

No. 15: John Riggins goes all the way, Super Bowl XVII

Facing fourth and inches at the Miami 43 and trailing 17-13, the Redskins give the ball to their tank of a running back, John Riggins. He breaks a tackle by Don McNeal and goes all the way for the touchdown. The Redskins take the lead and go on to win, 27-17.

No. 14: Kurt Warner to Isaac Bruce, Super Bowl XXXIV

No. 13: Garo Yepremian's goofy pass, Super Bowl VII

Dolphins kicker Garo Yepremian grabs a blocked field-goal attempt and tries to pass the ball, which slips out of his hands and into the waiting arms of Washington's Mike Bass, who takes it for a touchdown. All is OK for Garo though, because the Dolphins still win the game.

No. 12: Wardrobe malfunction, Super Bowl XXXVIII

Do we really need to explain it?

No. 11: Not so fast, Leon, Super Bowl XXVII

Leon Lett is about to give Dallas a 59-17 lead over Buffalo with a long fumble return, when Don Beebe comes out of nowhere to knock the ball loose.
