Do you not see four? Your really missing out. I think some guys even started worshiping it. We even started selling a book about four. Once you see it, you can join out super cool club and four based economy.

I think the joke is that there's indeed unequivocally just three, and that one of them still says four despite that fact, contradicting the readers expectations who normally for this format expects the middle thing to be something that changes with perspective (eg. 6 vs 9)
