I threw my five iron into the woods one time with no intentions of ever going to look for it. I was playing my last round with this particular set of clubs as I was going to buy a nicer, newer set the next day (a decision made well before I became angry enough to throw the club) and the whole time I foolishly was thinking that my poor play was a result of these "crappy old clubs." So, on #17 after I chunked my first five iron shot about twenty feet and then slicing the second shot deep into the woods on the second shot, I sent the five iron deep into the woods after the ball with a string of expletives following it. That felt good until I turned around and saw the disappointed look on my golf buddy's face, then I felt like a huge putz.
Now, I don't throw, toss, bag slam, or hit the ground/cart path with my club. I try my best to play the game as a gentleman and act accordingly.
