I have to admit, that playing a great game (and winning) is the most satisfying aspect of the game. However, I think you'll probably agree that watching bloopers that other golfers make is loads of fun!
Here's a video I picked up off YouTube that I think is hilarious. I'm hoping that you don't mind me putting this in place of another post -- for the moment, at any rate.
It's not specifically about using irons, but is just a riot to watch. Enjoy!
