I'll start. Fahrenheit is the superior temperature system for weather reporting. We should use metric for literally everything else, even Celsius for cooking, but I'll be dead in the cold ground before I abandon a system in which you actually get to experience both 0 degrees and 100 degrees. Freezing being 32 instead of 0 is literally the only downside, and it's not a hard number to remember. I'm prepared to die on this hill in the comments.
To up the ante further:
Base 10 is dogshit. It only divides evenly by 5 and 2. Base 12 is better, because it divides by 2,3,4, and 6. And you can still count on your fingers. Your four non-thumb fingers each have three segments. That's 12. Use your thumb to mark them while counting.

Universe brain = base 69
Multiverse brain = base 420
420 is divisible by the first 4 prime numbers, unlike the virgin base 60 which doesn't include 7.
Didn't a lot fo ancient middle and near east civilizations use base 12?
