When will celebrating fans learn?  It's just a bad idea to climb up on to a street sign to celebrate your team's victory.  We watched back in 2008 as a Phillies fan took a bottle to the head, knocking him off the street sign he was dancing around on.  That didn't stop the guy in the video below from climbing up on to a sign the other night to celebrate the Ravens' Super Bowl Win over the 49ers.  He climbed up, bounced around a bit and then paid the price.  How this guy was not cut in half is still unknown.
