I was just watching a show on Discovery Health about a child with abnormal strength. He was walking at 5 months. Climbing and decending stairs at 6 months. Doing pull ups at one year. The kid is going to be a freak athlete, it's obvious. The best part, his dad says "I'd love to see him play football for the University of Michigan someday!" Seriously, if you get a chance to watch this show, check it out. It's unbelievable.
update: here is a weird video featuring him..
