This particular gem came from a student in response to the question of what they thought visitors to Japan would find surprising;
"I think a visitor to Japan might find lowness of
men's toilet. In America or Europe men's toilets are installed
higher. Japanese men's toilets are installed very low because Japanese men
are shorter than European and American.
On the contrary, if we use the toilet in America,
we have to turn our Johnsons upward."
I am curious guys (as opposed to girls...) is it true?
