Nice, Sling.
I have another possibility. Find out a nearby course that he wants to play, and buy him a round. Then, make a day of it. Pick him up, ride with him in the cart (don't drive unless he asks you to) and spend the round catching up. Buy him a beer or two and dinner after. I'll bet he remembers that day for a good long time.
If you guys don't get along, then buy him the biggest, baddest nonconforming driver you can find. Call up his playing partners on the sly (the one(s) he bets with) and let them know it doesn't conform. He'll remember THAT day for a good long time too.
