We've long known the "Stick Season" singer is a stick (he was an entertaining guest on Golf Digest's The Loop podcast last year), but this is particularly impressive. Kahan made an ace on the 11th hole at Boston Golf Club, then thanked his caddies, his host and his "pure-ass 5-iron." Well said, Noah. And congrats. Looks like he got a head start on the celebratory drinks as well.
