From the excellent sports blog Awful Announcing,

So Tiger, Jack, Kenny Perry and Stewart Cink, all played together in the Memorial Skins Challenge this afternoon, and not only did Tiger take home the lion’s share of cash, but he also did so in a way only he could. There were four skins that had carried over to the 18th, and Tiger hit a clutch putt to deny Kenny Perry the win. With five skins now carrying over, the four players decided to have a closest to the pin contest from off the 18th green, and Tiger decided to show off by holing his chip….The guy is just insane. He’s donating the money to charity anyway, but that doesn’t matter. I used to think Michael Jordan was the most competitive person ever, but Tiger might have just taken over the number one spot.
