MUST BE A UNISEX RESTROOM

that's a christmas tree

It'd be fun to add some LEDs to the sign hehehe

its for the people with no arms for as the sign has no arms

Is such a person disarmed or unarmed?

Is it for one-legged caped heroes? The cape would provide cover....
Nah, the other suggestions are more likely, and more fun

seriously.
our target started making unisex bathrooms. it was gross, and we don't go to target anymore....
