WTF? Is calling it a prank even technically correct? I mean the guy who just got a door knob impression made on his forehead is laughing.
That's how fucked up Eastern Europe is. This guy hung upside down from that pull-up bar, full well knowing what was about to happen, and then he thought that shit was hilarious. Probably wasn't even the first time they've done this either. They probably have to flip coins or shoot rocks, paper, scissors to determine who gets to have their face smashed in next. I'd go as far to say that the pull-up bar has never been used for one chin up.
