This reminds me of a little story my professor told me about. He was working for a consulting company doing boat design and well, they took into consideration the ergonomics of "extra curricular activities", keeping in mind the legroom etc. and ceiling space as well as the rest of the surroundings of the cabin of the boat to facilitate it.

After this ridiculous design criteria, my prof proceeded to quit his job.
