Close. Lamps are used as a stand for a lightbulb. They're also a convenient place to put a switch. That they also offer a way to hold a lampshade is an added bonus, since it makes a lamp a much nicer thing to have in your room, rather than just a bare bulb.
Drills are indeed used to spin things. Often drillbits, but not always. I have a bit that makes the drill into a saw. I have another whole set that turn it into a screwdriver. I don't have, but you can buy, "bits" that turn a drill into pretty much any power tool. It is, after all, just a motor attached to a chuck.
A monitor is indeed designed to emit light. Light of specific colors, in specific patterns. The light from my laptop often lights my way across my bedroom in the dark. More often, of course, I use it to look at those patterns of light and derive information from them.
Don't you just hate it when your attempt at ridicule backfires?
