Anybody remember urinal.exe, a Flash game? Long gone but it illustrated the Code.
Then there’s this, more recent:
Finally, back in 7th grade, the boys’ rooms (at least) had these round sinks with a step bar to turn on the water, kind of like these:
A few years after that, I was at Maple Leaf Gardens for the first time, and they had round trough urinals. I was horrified, not because of the privacy issue, but because I thought guys were peeing in the sink! (Not that there’s anything all that wrong with that, but doing so in a public restroom is a bit over the top).
