SUPER-SIZE MOO: A hilarious video shows a cow peering out of the backseat of a car at a McDonald's drive-thru in Wisconsin

• A video of a cow peering out of the backseat window of a sedan car went viral this weekend.
• The video was taken by a Facebook user Jessica Nelson at a McDonald's drive-thru in Wisconsin.
• Nelson later found out there was not one, but three cows purchased at a livestock auction seated in the car's back seat.

A video of a cow sitting in the back seat of a sedan while it trundled into a McDonald's drive-thru went viral this weekend.

The video was taken on August 27 by Facebook user Jessica Nelson, a resident of Mosinee, Wisconsin, and shows what appears to be a large cow peering out of the window of a gray sedan car.

"A WHOLE FREAKING COW!!! Tell me you live in Wisconsin without telling me you live in Wisconsin," wrote Nelson, adding that the location of the cow sighting was at a McDonald's drive-thru in Marshfield, Wisconsin.

"I thought it was fake at first. Who puts a cow in a Buick?" she told the AP. "Then its whole head moved."

When interviewed by CBS affiliate WDJT-TV, Nelson said she was contacted by the owner of the sedan car, who told her that there was not one cow but three in the back seat.

"I found out this morning that there were actually three calves in the back seat of that car. Two of them were laying down and one of them, the one that you saw, was standing up," she said. Nelson was not told, however, why the cows' buyer opted for a sedan car as the chosen mode of transportation for their bovine bounty.

"Maybe we'll see other, you know, goats or pigs," Nelson told WDJT-TV. "Might become trending to take your livestock on vehicle rides."
