I was going to change a blown lightbulb in my living room, but after

Must I call in an electrician? It's quite dark in here now with only
my reading lamp. It makes knitting quite difficult.

If I can do it myself, how do I choose the right bulb? Is it illegal
to fit the old filament ones now? Do I have to get one of them LED
things to stop global warfare?

What about ladders? I was just going to stand on a small chair, but
apparently that isn't safe. I don't really want to buy a stepladder
(do I need to go on a course to use one?) just for one bulb, but it
might be cheaper than an electrician, unless he's good looking of
course, maybe I can answer the door with not much on and get a
discount.

Stand in a bucket of cold water and make sure your hands are wet, make sure
the switch is in the 'on' position and carefully smash the bulb with a steel
rod without the use of goggles.
You won't need the replacement.
