It's amazing to me that so many folks were worried about Dave's return...I never doubted it for a second. He has waaaay too much gumption, will and sheer brain power to let something as trivial as major back surgery keep him down. Why, he was already schooling trolls not more than a day or two later. He's a force of nature...with a sharp mind and a wry sense of humor. In short a man to be reckoned with...I reckon. Welcome back, ol pal.
