In Through the Out Door

I have a dear friend getting a colonoscopy and endoscopy this week on the same day. I’m concerned that they may do both scopes from opposite ends at the same time. What if the two scopes meet in the middle? What if the scopes meet and get tangled? What if my friend then has to have surgery to get the scopes untangled? What if the scopes meet, fall in love, and elope together to the gall bladder? I need answers to these questions, please. I am literally asking for a friend.
