My "super power" is so stupid, but it amazes the people I'm with. When I'm at a college or pro sporting event, if I'm told the stadium's seating capacity, I can guess that game's attendance and come dangerously close to what's listed in the box score. I was at the Browns-Bengals game in Cincinnati this past fall. The game wasn't anywhere close to sold out, so I couldn't just guess 65K, which is what Paul Brown Stadium seats. My guess was still within 1000. And on a related note, I can also sometimes guess how many people will be/were at a game based on how the involved teams' seasons are going, how important the game is, the stadium's capacity, and the passion of the hometeam's fanbase. This morning, I guessed attendance of a college basketball played last night that I didn't even watch or listen to and came within 50.
