Observation of the Day

I occasionally sleep with earplugs, which I buy in packs. Over the years I've periodically replenished my supply, but not without noticing that there is always a singular earplug remaining in the old bag. Hm.

One would think that since, you know, we have two ears the earplugs would come packaged in some even number. I suspect this is not the case.

Please note: I cannot confirm this because the cardboard packaging has long since been thrown away. I can only speak to my speculations and the lonely earplug remaining in the bag. I also do not care enough to earnestly look into this problem.
