our bathroom door
is very interesting. It doesn't have a knob. To get in, just give it a push. It doesn't have a lock either, so if you want to use the bathroom, you just push the door shut (it has a latch somewhere that allows it to stay shut). To get out, a hook will help you pull the door open. :)
It has a poster of West Side Story which we watched when the show ran last year at the Meralco Theater,
and this little warning sign. I'm sure my cat knows how to read it by now. The bathroom is off-limits for him because he used to poop in the hard-to-reach areas. Haha.
