The backstory goes like this: Improv Everywhere—a group that sets up unexpected events in public places—was recently contacted by ESPN for a stunt involving the Claret Jug. Yes, the real Claret Jug, the trophy that is easily the best in golf.
Improv Everywhere came up with this idea, an inspired stunt where they crashed a mini-golf course on New York City's Pier 25 and turned it into a mini-British Open, complete with TV cameras, galleries, caddies and ESPN announcers. To add to the authenticity, they even contacted the Royal & Ancient golf association (which puts on the British Open) to use their "quiet" signs, caddy bibs, and golf flags.
The kids who got treated to this obviously really enjoy it. Try not to smile when Isaac drills the final putt to win the tournament.
