Little town I frequently drive through has a population of 1337.

I always have a little giggle.

come to think of it, doing a separate list of toLower l -> 1 isn't a bad idea either...

pager code, probably better. "143" = I love you; but 177427*711773 = what time. I don't miss those days. I never had a pager, and i managed to convince all my friends that they shouldn't, either, by pager bombing them. Pagers are still in use, and they're plaintext over the air so if you live near a place that uses pagers (hospitals still use them, for instance), you can get all the messages in real time. It's the frequency. It's in VHF (iirc) so it goes places microwaves cannot; it's also low bandwidth, so the small spectrum carved out for it is usually enough for hundreds of pagers in the area.

And since there's no real place to mention this elsewhere, there's a HTML color bot on fediverse (botsin.space) that periodically posts two colors, that work as compliments as foreground and background, and vice versa. I haven't seen it in a while, but our little instance has gotten popular so the feed rate is up near a few hundred posts an hour to sift through.
