We went to Copenhagen this summer and visited a few of their castles. One of them had a wetting throne on display. It was a chair that when an unsuspecting guest sat in it, it had springs that would activate clamps to hold the person in the chair and a water bladder in the seat would then trickle out water to make it look like whoever sat their had wet themselves. It was quite interesting and a fun gag at the time apparently.
We also visited Kronburg castle (the setting of Shakespeare’s Hamlet) and they had one of the largest ballrooms of the time. Guests would be expected to eat lavish meals over a period of 18 hours and were provided feathers and pot so they could induce vomiting so they could continue to eat. I wouldn’t mind experiencing the splendor and silliness of it all with my family.
