Several stray cows bellied up to the bar for a few beers in a backyard.
"They enjoyed it. There's no doubt about it. They went right for the beer and then when one was done, they'd knock another one over and take care of that beer," said Lt. James Riter of the Boxford Police Department.
Boxford Police say they heard screams and then a group of women took off when about five or six bovines crashed their backyard party.
The thirsty cows eagerly helped themselves to the beers left behind.
"They got up as the cows went towards the table. They stepped back and the cows took over the table, knocking over the beers with their noses drinking the beer off the table. They went to the recycling bin to find any leftovers," Lt. Riter said.
In a 911 call, one person told the dispatcher, "We thought they were deer, but they're huge, huge, huge cows. There's got to be five or six of them."
One of the calls came from Andrea Poritzky.
"I just went downstairs, and I have about six cows in my yard. I don't own cows," she said.
"I was initially a little nervous. And then after I found it very comical and not very surprising due to the fact that we live in the country here," Poritzky said.
The cows were eventually rounded up and with a police escort, returned to their farm about a mile away.
The cows are home safe and sound and no charges were filed.
