Three-time major champion Padraig Harrington is in Bermuda this week to take on Masters champ Adam Scott, U.S. Open winner Justin Rose and PGA Champion Jason Dufner in the PGA Grand Slam of Golf  at Port Royal Golf Course.
On Sunday, Harrington -- the defending champ of the event reserved for major winners -- put on a little show at the driving range with his impersonation of Happy Gilmore.
Have a look:
Chances are you won't be seeing Harrington break out that swing in the actual tournament, which takes place Tuesday and Wednesday.
