Yeah, someone is getting arrested for that prank.
Oh look, he already has. From WTVR:
The naked man filmed pouring milk on himself and screaming at a Kentucky Walmart was arrested and taken to jail over the weekend. The video was posted on YouTube, but later removed due to the nudity. The man in the video was wearing nothing but shoes, socks and a Halloween mask.
“Well the first question I would have is why? Why would he want to do that? They can go to jail and they will go to jail,”
Pike County Sheriff Rodney Scott said.
Over the weekend Sheriff Scott’s deputies arrested David Daniels and Timothy Smith, according to WKTY.com. Both men were taken to jail and ordered held without bond pending a Monday hearing. It was unclear which man was accused of streaking and which man was accused of recording the streak.
