Restroom Sign WIN

A while ago there was some discussion about sex-segregation in public restrooms. Some clever folk at my school put up these two signs:
These were put up at the entrance to the library bathrooms, which for most of the year had been unmarked.

There were two unmarked restrooms in the Music and Dance building where I take choir. Recently, someone put up official looking Men/Women signs on the doors (and I discovered I had been using the “wrong” one without realizing it.) A few days later, these were replaced with the picture “whichever” signs, which were themselves taken down, leaving the doors unmarked.
My choir director has said the issue of restroom signs has been a controversial issue for years here. It does seem kinda silly, especially given that we share restrooms in the dorms.
