Wear high socks, a plaid outfit, golfer hat, carry golf clubs and tee.
Thanks to Lucky Clover for this fun, easy idea.
Another Idea - Dead Golfer
Hey! My idea is the dead golfer. Cut a golf ball in half and glue it to the middle of your forehead.
Put fake skin and blood around it for the realistic effect. Wear regular golfer attire and carry a golf club. You could also put the golf ball as an eyeball and be an alien!
Thanks to Kristina for this clever idea.
