Golf Club Drink Dispenser

I recently took up golfing which is a good way to get some "exercise" while enjoying the beautiful Northern California summer weather. I am doing pretty good, but now I am on a quest for accessories to enhance my golfing experience. I found this somewhat amusing way to carry my drinks. The Electronic Drink Caddie looks like a regular driver, but it has a secret button to dispense your favorite drink, hot or cold. It doesn't take up space and will stay at the right temperature. It holds 54oz and runs on four AA batteries. Problem is, it costs $99. Guess I'll wait until after I buy accessories that will actually improve my game. Also at Brookstone.
