Here's something you don't see every day - even in a town as crazy as Chicago.

Police say this man, 24-year-old Christian Poole, tore off his clothes and began punching the windows of passing cars.

"He was really naked," prosecutors said, according to DNAinfo.com.

He even stepped out in front of a city bus - and when cops arrived, he didn't go peacefully. He went on the attack, trying to choke one of the arresting officers.

Ready for the punchline? Poole has a tattoos that says "Work Hard Play Hard."

Maybe he should add "Be Naked" to it.

By the way, note the "Part 1" here - because Poole isn't the only naked man to allegedly go nuts lately.

There's a sequel to this coming up later in this gallery.
