Hint: The Riverdance:
Play a game in the season mode and save it. Then, go to the main menu and select "Blitz Theater". Choose the now unlocked "Exhibition FMV" and see the Midway Team winning a game. Then, the players will get in line and do the Riverdance.

Hint: Onside kick:
Hold L + R + Z + A + Up to do a great onside kick. It does not go as far, but they will fumble it often and you can also catch it.

Hint: Easy sack:
Flip a play on defense, but return the man who is going to blitz to his original spot. You have a better chance of sacking the quarterback.

Hint: Dolphin swim:
Enable the "Dolphin" player code and start an exhibition game. Wait for your player to do The Worm for a touchdown celebration and it will appear as if the dolphin is swimming.
