Daniel Park Cup
A League of Legends tournament with one entry requirement, which was being named Daniel Park. It ended in an arm wrestle.

The idea
There are a lot of us. I wanted to find out what happens if you give one hundred people who share a name a reason to be in the same room.
How it came together
Riot Games sponsored it. The winner was a Master-ranked Daniel Park from Chicago, who was considerably better at the game than the rest of the field.
He was flown to Toronto, and it was settled with an arm wrestle in Yonge-Dundas Square, outdoors, in front of whoever happened to be walking past.
