Vaseline?

[Sevenfold]

It will give you more distance as the ball clings to the club an extra fraction of a second. I heard about this and tried it on my own in a practice round years ago. First tee I gained about 20-30 yards. Hit it a couple more times, same results, but lost interest because as others have mentioned, it's cheating, so why bother?

However, if you are playing with a group of buddies and want to risk getting a beat down, chapstick is the best bet for not getting caught.
