This is why I love watching hockey. [After clicking on the link, click on "Launch Motion Player Now" at the bottom. It will play an ad (you can skip it by hitting the Skip (">>|") to the right of "Guide"), then highlights of a hockey game.] Just after halfway through the clip, in the Overtime segment, comes perhaps the hardest (clean) check I've ever seen. Keep watching, they'll show it again in slow-mo and another view for good measure. It looks like the guy's entire nervous system goes through a system reboot in the seconds afterwards.
