Oh my god, oh my god, oh my god, it’s a urinal that disappears into ground! It’s a public toilet that might bury you alive!

ADDENDUM: I was attempting to describe the function of this toilet to someone who assumed that it was actually supposed to go underground with you in it, you know, for privacy. That is not the case. “Like the ‘maneater’ that Hall and Oates sang about,” I said, “those urinals ‘only come out at night.'”
