As an Australian man travlleing the US for a few months half a decade ago, I was genuinely puzzled by the very high water level in some of America's toilets - so high that sometimes you have to hold your undercarriage up to keep it from getting wet when sitting.

I asked several locals during my visit about how to deal with this oddity, and all I ever got was laughter. I still don't know what the supposed method is... :)
