My  sister is an RN on a post-ortho surgery floor.  So mostly little old ladies with hip/knee replacements.  However, they get overflow from the med floor.  She came home one night and told me a story of how they were transferring a bariatric beast from chair to bed using the crane thing and the bitch couldn't hold its bowels while being moved.  It shit all over itself and the nurses, while in the air.  In the air, maybe 30sec worth of holding its shit in before bed pan access.  But no it chose to shit itself while trussed up like the pig it is.
