Not a large capacitor in my case, but I took apart my old camera after it stopped working, and accidentally touched the capacitor for the flash. A memorable moment.

And people don’t realize how long they can hold power after the device has been “off”.

Edit - I forgot to add my thing! A good example of something that doesn’t sound scary is a TV, but it has large capacitors that can end you (or make a bad day).
