There are 10 types of people in the world: those who understand binary and those who don't. Read in base 2, 10 is two, so the sentence is an accurate count that only half its audience can parse. The shirt prints the long version, with kinds instead of types, the way it has been passed around programming forums for decades.
For programmers who work with binary and appreciate wordplay that only makes sense if you know base-2 counting. Simple text design stating the joke without explanation. Works if you get it immediately without needing it spelled out.

The blank behind every t-shirt
Most brands treat the blank as an afterthought. We treat it like the product it is. Every design ships on the same tee we picked after ditching the ones that pill, shrink, and go see-through by the third wash. Proper ring-spun cotton, soft enough to wear five days running, tough enough that the print still looks new long after your last deploy. True to size, no surprises. The kind of shirt you forget you are wearing, which is exactly the point.
