The audience names ANY playing card and it is inside your mouth behind a layer of duct tape.
You walk out on stage with duct tape wrapped around your face and scream at the audience to narrow the deck from 52 down to one card. When you take the tape off of your face, one card cleanly comes out of your mouth and when you unfold it, its their card. Every time, any card. No force. No magician’s choice. Any card.
