Happy National Classic Smoke Alarm Day!

It’s 4/6. Get it?
This idea just popped into my head, so I went with it.

I’m not sure I get it so I am hoping even though I’m about a month too late that you can explain it. :lol:

“4/6” is the name of the coding pattern used by old (pre-Temporal 3) smoke alarms, this one: https://www.youtube.com/watch?v=utn4Mrd9BcM

Correct! In hindsight, I’m not surprised only one person got it, as it’s quite an obscure factoid.
