Note to Aspiring Artists:
Your girlfriend is having her right buttock abscess drained by the doctor.
This is not the time to ride the hospital elevators and graffiti on the elevator walls.
There is a security camera. You will be seen by security. You will go to jail.
Although if you must decorate the walls I would appreciate:
"Dr. Winters gives good moderate sedation!"
Or perhaps something a little more eloquent.
