Imagination is a big help to find the funny in hospital life.  

• When I was "fed" nutrients through an IV, I referred to the bag as my cheeseburger and Amstel Light (yes, it was awhile ago).   "Can I get some ketchup, please?"
• Every lap around the hospital floor, pushing my IV pole, was training for the hospital Olympics.  Break the silence by humming the Rocky theme song or singing to a tune playing through your ear pods.  You don't know how you sound, but the staff will let you know! 
• What if you're not dry enough for your nightly dry weigh-in?
