Apologies to anyone who gets this in their mailbox twice — I’m not sure what happened the first time.

According to various unreliable sources on the Internet, tomorrow is National Clean Out Your Refrigerator Day. Although this holiday has some major flaws — I don’t get the day off from work, and I’m pretty sure I’m supposed to spend it cleaning out my refrigerator — it’s still my favorite. Why? Because its very existence implies that most people clean their refrigerators just once a year. I clean mine at least twice that often, which means my fridge is twice as clean as the national average, which makes me feel smug and superior, which is my favorite way to feel, which makes this my favorite holiday. Also, I don’t have to cook anything, buy presents, or give out candy. I don’t even have to clean out my refrigerator, really, because if anyone looks, I can just say I’m keeping stuff in there for National Science Experiment Week — which technically doesn’t exist, but who’s going to check?

Actually, why isn’t there a National Science Experiment Week? Doesn’t that sound like it would be at least seven times as much fun as National Clean Out Your Refrigerator Day? I’d probably celebrate by running a small-scale version of that experiment where neutrinos probably didn’t travel faster than light, using the particle accelerator in my basement. Just kidding! I don’t have a basement. But I do have a particle accelerator, which I got for $19.95 at the pet store (it was marketed  as a cat toy, possibly because the particles that it accelerates are arranged in the form of a toy mouse). And my phone has a stopwatch app, so I’m all set — or I would be, if National Science Experiment Week really existed. But it doesn’t, so I guess I’ll just clean out my refrigerator instead.

A note to anyone reading this outside the US: apparently there is no International Clean Out Your Refrigerator Day. I’m sorry you have to miss out on all the fun.
