For some reason I don't think this would have been to much fun for the passengers.

Apparently, the Rudder Trim knob is near the Cockpit Door Lock release knob.
One is big enough to palm and is round (rudder trim) and the other is small and "bladed" (door)

Not really sure how you can't tell which one you grabbed.
