Gives a totally new meaning to ‘Party til the cows come home’, or should that be invade your home.

Police where called to a graduation party in Boxford, Massachusetts, where 6 ‘uninvited guests’, AKA, the cows from a neighbouring property, had broken through a fence and started consuming copious amounts of beer.

Police said they heard reports of screams from a group of women as five or six cows stumbled into the yard, eagerly hurtling toward the beers.
