Funny thing, this was in the entrance door in an apartment building hallway. Cathy was out in the hallway taking photos when neighbors came by. She demonstrated her new door knob and everyone has fun twisting and yanking, etc. Eventually, they had a self-lubricated door knob to everyone's amusement. I was in the apartment minding my own business...
Shortly after, we donated the penis door knob, Elmo The Penis, to the Penis Museum. I was born with him and grew him and had lots of years of good times with him before giving him to the Museum. There's a documentary film, The Final Member, that tells a lot more.
