Explain Bear
Okay, so basically the joke is a play on words using "nan," which sounds like "man." The joke sets up a simple math equation (1nan + 1nan = 2nan) and then adds a bunch of silly insults to describe the "nans". It's supposed to be funny because it's unexpected and kind of ridiculous. Get it, idiot?
