A party in Boxford, Massachusetts went a little sour when it was crashed by the worst types imaginable—the type of party-goers who reek, physically intimidate guests and steal everyone's drinks—cows. About a dozen young adults were having a backyard get-together when six cows wandered in from the road, amusing some of the guests and causing others to scream. But when it became apparent the cows weren't just passing through, the partygoers abandoned their picnic table and beers, not wanting to start any beef with the bovines. This didn't end the festivities though, since the cows seemed determined to milk the party for all it's worth—knocking over cups and slurping beer and leftover drinks. One cow even tipped over the recycle bin and drank the cocktail that spilled out. “They seemed to prefer the Bud Light,” observed Lt. James Riter. By the time police arrived on the scene, the cows had left the party, but Riter found “evidence” confirming they had been there—the kind you wouldn't want to step in. He tracked them down to the front yard of the house where the cows' owner came to claim them, and together they were able to nudge the cows back to their field. Whether the cows tipped themselves after the party remains unknown.
