If all of the digits summed recursively reduce to a 9, then the number is divisible by 9 and also by 3.
If the difference between the sums of alternating sets digits in a number is divisible by 11, then the number itself is divisible by 11.
That’s all I can remember, but yay for math right?
Or “Wagpn Wheel”.

Don’t forget to yell out “Free Bird” you clever bastards.
I always liked to mic check with “pop-, pop-, popsicle, ice-, ice-, icicle, test-, test-, testing 1-2-3…”
It truly is the forgotten pandemic.
Correct, the source of the fever was never specified, all we know is that the only prescription was more cowbell. This was a real concern for the CDC and the WHO at the time, but the fever appeared to subside on May 21, 1976, when the song “(Don’t Fear) The Reaper” was released by the Blue Oyster Cult, potentially saving millions of lives.
What do they do, make you take a urine test to see if you’re topped up? That’s lunacy.
There’s this thing in Canada that most grocers belong to called the Retail Council of Canada’s Scanner Price Accuracy Code where basically if the price that shows up on the scanner when you’re paying for your stuff is inaccurate and it’s higher than the stated price on the shelf or in the flyers that you get the item for free or up to $10 off if the price is greater than $10. This would presumably not fly here if they tried upping the price on you at the cashier or the self-serve scanners.
So, pro tip to Canadians: watch what you’re paying at the scanner, ‘cause you can get a pile of stuff for free if you’re paying attention.
This one’s even faster, in fact.
But forget that, let’s talk about these Nano Cats.
There’s also the classic “no three positive integers a, b, and c to satisfy a**n + b**n = c**n for values of n greater than 2“ trick but my proof is too large to fit in this comment.
