If you are not a golfer, avoid at all cost any kind of silly or goofy golf-theme gifts. These are useless and a waste of money. Unless you know the golfer and his unique needs, for example, what kind of golf ball does he play with, it's usually best to treat the golfer to a gift certificate from a good pro shop. You can't go wrong.
