Colonoscopies are unpleasant. You need to go to the doctor, get naked, and have this stranger do very awkward things in an uncomfortable place on your body. Unfortunately, they're very necessary if you want to detect and prevent colon cancer. What are you to do?

Just do the colonoscopy yourself with this delightful hand-held endoscope. And really, you can use this thing in all matter of dark places, not just the one obliquely hinted at above. It's got a screen on the handheld unit allowing you to see where your snake is looking. So many uses! How can you say no?
