My mom got a colonoscopy in June 2009 and woke up and said, "When are they gonna give me the colonoscopy?" HAHAHAH! She then proceeded to eat like a cow.
Afterward, she said she wanted to go on the "colonoscopy diet" every month just be able to eat like that again!
Not making light of the situation, as it is certainly serious, but the miracles of modern medicine are AMAZING! Order a pizza before you go in and it'll be ready when you get out!
