A common aphorism of the early 21st century:

There are 10 types of people in the world:

those that understand binary,

and those that don’t.

Wait, that’s not quite right, let’s try adjusting it…

There are 10 types of people in the world:

those that understand binary,

those that understand ternary,

and those that don’t.

Better, but it feels like something is still missing. Let’s run with it…

There are 10 types of people in the world:

those that understand binary,

those that understand ternary,

those that understand quaternary,

those that understand quinary,

those that understand senary,

those that understand spetenary,

those that understand octal,

those that understand nonary,

those that understand decimal,

those that understand undenary,

those that understand duodecimal,

….

those that understand hexadecimal,

….

those that understand vigesimal,

…

those that understand sexagesimal,

…….

and finally, those that understand the futility of applying Hilbert’s Paradox to an ambiguously based number.

Ah, that’s it. Unfortunately, it won’t fit on a T-shirt.
