I am going to level with you... there is probably nothing in this world that gets on my nerve faster than somebody who takes themselves too seriously. Well, except maybe cats... I think I am mildly allergic and they always try to sit of my face.
That aside, I believe that it is especially true of hobbyists and gamers that you should be able to make fun of yourself a little bit and enjoy the humor inherant in your hobby. I mean, if you have stopped laughing, you have probably stopped smiling, too, and that is what gaming is all about!
Of course, that is why they created Larry Leadhead. Larry is the star of a little internet comic strip about miniature gamers that I stumbled across a few years ago. I soon found myself nearly in tears I was laughing so hard, and Larry has been one of my favorites ever since (especially his comprehensive list of the reasons that spouses and girlfriends don't like you bringing your wargame group back to the house... where else can you find out what happens when you give a hummingbird coffee?).

Hopefully you get as much enjoyment out of it as I have.
