I was going to tell you this whole thing about how today I discovered that I grind my teeth, and that's the reason for my aching molars, but it really wasn't that interesting, or funny.
Instead I will point you in the direction of the article archive for The Wave. In particular, the articles by Harmon Leon. They kept me company during an unusually slow day at work yesterday. And they are far more amusing than my teeth grinding story would ever have been.
