Actually, Spaw, I really enjoyed my colonoscopy except for the total weirdness of the entire concept, the extreme discomfort and the sense that the end of the "hose" would soon find an exit through my mouth!

If there is a next time, or for those who haven't yet had the experience, ask if they have a "teaching scope". This wonderful device splits the fiber-optic view that is normally only seen by the clinician and allows you to see what there is to see. It is not unlike watching a video of a portion of a Disneyland adventure ride through Magic Mountain or whatever. But then, I'm rather easily entertained...
