Here’s a light bulb joke for you. How many geophysicist/novelists with the name Rojstaczer does it take to change a light bulb? It better be no more than one because finding two geophyscist/novelists with the name Rojstaczer is, in fact, impossible. Hahaha.

I’ve been changing out light bulbs in my house because my eyesight is iffy and is especially bad under low light. Out with the curly fluorescent 23 watt and less light bulbs. In with 23 watt LEDs. The difference has been amazing. Our house is no longer a fuzzy cave for me in the evenings.

Changing them out has taken me about one minute per bulb. That’s no joke! But I’m not going to be able to tell another light bulb joke for a long time, maybe never again. The boxes that housed the new bulbs say they’ll last 22 years. 22 years! I may well be six feet under the next time a light bulb goes out in my house. How can you tell a light bulb joke when you never have to change a light bulb?

My plight is not personal. Over the next few years just about every fluorescent and incandescent bulb in the world will burn out. What will they be replaced with? LED bulbs, of course. When that happens, light bulb changing worldwide just might stop for 20 or so years. How many people worldwide will be needed to change a light bulb? Zero. How about the year following? Zero again. The light bulb joke will have to go on a two decade hiatus. It will be, temporarily, the dodo bird of jokes. It may well become the 22 year cicada of jokes. Ten years from now when you try to tell a light bulb joke to your kid/grandkid, you may get the same stare you receive when you mention Blockbuster or telephone booths.

We’ll need other jokes about incompetence to replace them. Here’s one. How many doctors would it take for Americans to obtain decent health insurance? One, a surgeon capable of implanting backbones into 218 slimy, slithery congressmen. Hahaha! I’m sure you can think of a bunch of “how many“ jokes on your own.
