I have come across bouncing jelly. No word of a lie, the darn stuff bounced at least twice when you threw it on the floor - it was uncuttable. Asparagus for breakfast (Ewwww).
One poor chp in ICU, due for D/C to ward that day little appetite but what did the kitchen in it's infinite send him? On a white plate was a white piece of fish in white sauce and neatly arranged at the side was a..... wait for it ...... serve of spagetti bolognaise!!! There are some smells in this universe that God never meant to combine - fish and Spag Bol are two of them!!!!
The winner though happened during my training. Little old lady on a 20 grm Protien diet. Renal failure - badly fitting dentures and the kitchen sent her a, well the only term appropriate is "leathered", steak. Black and so tough it fought back.
The RN muttered under her breath - offered it to the patient so we could say that we had done so - then taped that sucker to the plate. When the dietitian came up later in the day she held up the plate vertically with this black piece of hard leather curling around the tape. To this day I do not know it that bit of steak had curled through drying or it was trying to escape. It had the desired effect - the meals got better.
