Shooter McGavin: Hands-On Golf Pro ... Just Taaaaap It In

Shooter McGavin took a page out of Happy Gilmore's playbook by giving a hot bikini clad comic swinging lessons ... on the green.

Christopher McDonald, who played the sleazy golf pro in the Adam Sandler flick, showed up at a $10 million hole in one tournament in Las Vegas. He didn't win the tournament, but it's hard to say he lost -- based on his interaction with Kate Quigley.

Still, nice to see Shooter finding his happy place ... just like Happy.
