A purge

No, not in the political sense as in Powell by Bush or CNN by Ahmadinejad, but as in Thunderstick by Fleet in anticipation of his screening colonoscopy. Tomorrow, after 24 hours without food, two doses of the emetic (I think they would call it that), many quarts of clear liguids, and God knows how many times on the throne, they'll be photographing my insides via a long tube with a tiny camera. I hope the business end doesn't come out my nose and that it doesn'f find anything suspicious. I'm assured by friends who have undergone the procedure that it is really nothing to be concerned about, but the imagination reels. So reel it in, Thunderstick, and you'll be much better.
