Not about dumb pax.
Finish collecting trays after supper service. Lights dimmed, returning to galley with last full cart. There is a hair piece caught in the door of cart. Walk back down the aisle looking for bald pax. Find him sound asleep...... definitely him as the double sided tape bits still attached to scalp. Gently place the toupe back on his head. Next morning during B'fast I notice he is happily eating his breakfast, except in the dark I had put the hairpiece on back to front.
