Showing up to events uninvited is a science. Unlike the unbelievable success of Vince Vaughn and Owen Wilson's characters in 'Wedding Crashers,' the brave attempt usually ends with the spontaneous guests escorted to the door. In Boxford, however, it was a herd of cattle that killed the moooooood and sent the attendees packing.

The police on duty reported receiving a call about a couple of loose cannons who strayed from their home turf. When the cops tried to corral them in the front yard of a neighbor's house, the party animals took off for the backyard where they scared off hosts and guests enjoying some Bud Light and Miller Lite. They then knocked over floaters to get their slurp on and even went foraging through recycling bins to keep the night going.

The folks at Anheuser-Busch should be happy-- the bovine showed a preference to Bud Light. We can see this turning into a meme -- instead of cow-tipping, it's cow-sipping.
