Cows crash party and help themselves to beer!

Massachusetts' Boxford police Lieutenant James Riter said that he was responding to a call for loose cows on Sunday and spotted them in a front yard.

Riter said that the herd high-tailed it for the backyard and then he heard screaming.

The police Lieutenant said that when he ran back there he saw the cows had chased off some young adults and were drinking their beers, according to online news reports.

Riter said that the cows had knocked the beer cans over on a table and were lapping up what spilled.

He further said that they even started rooting around the recycled cans for some extra drops.

Riter said the cows' owner and some friends herded the cows back home.
