One of them was to remove the doorbell, which was extremely loud as the previous owner of the house was very old and hard of hearing. I started unscrewing the push button on the the door jamb and there was a bang etc
A handy modern gizmo for non leccy people is an electric field detector, places like Lidl and TKmax have them in stock from time to time for around a tenner
Point it at a wire or appliance and the LED lights up if the target has a live wire present, you don't need it to touch any exposed wires to work, (this blue one for instance tells you if 100 to 250v is present)
Mine told me all my old storage heating sockets are still live (the heaters are long gone)
Also handy for finding a broken connection point in a cable, the detector light goes out at the break
