There's a cathedral having some repairs done, and the workers have rigged a "cage lift" inside so they can get material up and down to the upper floors.
A characteristic of these 'cage lifts' is that the doors (gate) must be closed manually for them to be 'called' to another floor.
One day one of the workers, Peter by name, takes the lift to the top floor, and it is subsequently needed on the first floor by the sexton.
Unfortunately, Peter forgot and left the door open.
After the sexton rings for the lift a couple times, to no avail, he yells up for the worker to send the lift back down.
Visitors to the cathedral were treated to this sight:
The sexton of the cathedral, head tipped up, yelling to the heavens: "Peter! close the gates."
