Boo! Happy Halloween everybody! On Monday night the New England Patriots dressed up for a Halloween costume party at a local roller rink. In 2009 the Patriots held a similar event and Bill Belichick called it a "team-building activity." The same can be said for this year's party, as everyone was all smiles. From reading each player's Twitter feeds, it seemed like a night full of roller skating, laser tag, and drinking. Here are some of the best photos from the party:

Bill Belichick and his girlfriend Linda Holliday as pirates.

Tom Brady as The Cowardly Lion, and his wife Gisele Bundchen as Dorothy from The Wizard of Oz.

Kyle and Vashonda Arrington as Batman and Catwoman.

Brandon Bolden as a Call of Duty soldier and Marcus Forston as a SWAT agent.

Rob and Paige Ninkovich as Ancient Egyptians.

Here's the best picture of the night, with LeGarrette Blount, Aqib Talib and Brandon Spikes posing together. I don't know what Talib is, but I think he's my worst nightmare.
