NYC, Boston mayors in Super Bowl gun-control ad

NEW YORK - The mayors of New York and Boston are rooting for opposing teams in the Super Bowl. But they're on the same side when it comes to pushing for stricter gun-control laws.

That's why New York City's Michael Bloomberg and Boston's Thomas Menino have filmed a gun-control commercial that will air during Sunday's big game between the New York Giants and the New England Patriots.

The ad was shot Tuesday and will be shown in the Northeast, not nationally.

It shows the two mayors sitting on a couch as if they're watching the game. They're wearing Giants and Patriots jerseys over their shirts and ties.

Bloomberg and Menino are founders of Mayors Against Illegal Guns. The group has pushed for a stronger federal background check system.

On Monday, Bloomberg announced that the two mayors made a friendly bet on the outcome of Sunday's Super Bowl.

If the Giants win, a New York City family will receive a free trip to Boston, complete with a stay at the Ritz Carlton, dinner at Legal Sea Foods and box seats to a Bruins or Celtics game.

If the Patriots win, a Boston family will get a trip to New York paid for by tourism-industry companies, with dinner at the Russian Tea Room, tickets to "Phantom of the Opera" and a VIP tour of the Metropolitan Museum of Art.

Bloomberg announced that residents of the winning city will be able to enter an online lottery after the Super Bowl.
