John Daly recently hit a ball off a tee during a recent taping of the season finale of Golf Channel show host David Feherty's show Feherty. Normally there's nothing special off that, except that this time the tee was being held in Feherty's mouth while he was lying down on the ground.
That's some good concentration and focus by Daly, and some nerves of steel displayed by Feherty.
