Around 2:20 in the on Saturday morning, a cop was standing on the street, talking to a bus driver near a bar in Mankato, Minnesota.

The bar had just closed, so drunk people were pouring out of it, including 24-year-old Riley Swearingen, who was with some friends. Apparently just to get a laugh, Riley decided to sneak up behind the cop and give him a wet willy.

More specifically, Riley went with a double wet willy, meaning he put a finger in BOTH of the cop's ears at the same time.

At which point the cop spun around and saw him walking away. And if he wasn't already sure Riley did it, he was a few seconds later when he clearly heard him yell to his friends that he, "just gave that cop a wet willy!"

It turns out Riley is an air traffic controller in the Air Force and was in town for a friend's wedding. Initially, they charged with him "assaulting a police officer with bodily fluids," which is a felony.

But after three days in jail, a judge let him plead guilty to disruptive intoxication instead. So he ended up with time served and had to pay $77 in court costs.
