Surprise, it's Pete Carroll!
Carroll meandered into John Clayton's live shot during SportsCenter on Tuesday afternoon, presumably to find out for himself whether or not Clayton is hiding a secret ponytail.
Clayton was just trying to deliver the latest news on the drama between Adrian Peterson and the Vikings.
This is the danger of doing live television; you can get pranked by Pete Carroll.
UPDATE: Yep. He was looking for a ponytail.
