Hah!
When I was in the ER after being escorted by the police, I was ranting and raving, demanding that they let me go home, screaming at the ER psychiatrist et cetera. They put one of those paper patient bracelet IDs on my wrist. I ripped it off screaming "I AM NOT A ******* PATIENT!!!!", crumpled it up, and ate it. Just swallowed it up. The whole ER staff's jaws dropped and some of them suppressed a laugh. It was ridiculous but in hindsight pretty funny. My husband said that after that they gave me enough Ativan to kill a horse.
