Mayor Michael Bloomberg and Boston Mayor Thomas Menino are starring in a Super Bowl ad to promote their Mayors Against Illegal Guns campaign. The ad features both men clad in the jerseys of their city's respective teams talking about how they "don't agree" on sports or local cuisine.

"But we both support the second amendment," Mayor Menino says in the ad.

"And believe America must do more to keep guns out of the hands of criminals," Mayor Bloomberg adds.

Mayor Bloomberg and Mayor Menino are the co-chairs of the campaign, which began in 2006 at a Gracie Mansion summit hosted by both mayors. Since then, the coalition has grown from an initial group of 15 mayors to include over 600 mayors.
