I know this is a joke, but wrong about what, exactly? I don't get it.

Also, and maybe this has something to do with the joke I'm not getting, the way complex numbers are motivated in school is a lie, and a stupid one. Mathematicians were perfectly comfortable with certain equations having no solutions; the problem was when their equations told them there were no solutions when they could see the solutions: the curve x^3^ - 15x + 4 crosses the x-axis, but Cardano's cubic formula gives up due to negative square roots. Imaginary numbers were originally no more than an ephemeral reasoning tool, and were only reluctantly accepted as entities in their own right because of how damn useful they were.

If I'm not meant to think about it until understanding emerges, then that means it should be immediately understandable without thinking. It is not.

Sometimes it's better to just accept that you don't get the joke and move on.

I might not find a joke funny, or I might not have the necessary context to appreciate it; that's "not getting" a joke. If it's possible to have too much context to appreciate a "joke", it's at the expense of people who know more than the audience.

Bruh, who cares.

Stop complaining.

It might seem harmless, but the purpose of a joke is to draw a distinction between those who get it and those who don't, fostering a sense of community. In this "joke", the in-group is people who don't know something; the community ideal fostered there is that knowledge is undesirable, that anything that seems unintuitive to the uninformed mind is inherently ridiculous. The "joke" has no effect if it doesn't do this. Entertaining the idea without challenge is dangerous.

That, there, is the story of pretty much all maths. There were occasional mentions of zero and debates about whether it's a number or not in old Europe, it only became widely accepted once base 10 became popular. And people still can't agree whether the natural numbers contain it!

Hah. Church tried to ban it because it was "associated with illegal money trading", I remember that. What is it about maths that makes non-mathematicians think themselves qualified to judge matters they don't understand?
