Overcoming preconceived notions of what to expect based on what they look like is a staple of reality shows (see: Susan Boyle). And just because we've seen it before doesn't mean it gets any less amazing.

Case in point: the dancing duo of Paddy and Nico on 'Britain's Got Talent.' Paddy is just shy of 80 and the judges and audience hardly seem impressed with their salsa, at first. But then the pair kick it up and put on a show for the ages.

The performance was just plain fantastic. It must've been -- Simon was forced to apologize for hitting his buzzer too soon.
