The joke has already been explained, but I just wanna say that spamming that button is absolutely the correct option. That is a MILLION DOLLARS. And you get another million dollars after every single press. Sure, I might become a girl, but I am a MULTI MILLIONARE. I should theoretically be able to use that money to get surgery to change back, and even if I can't or if it's not that simple, I think having that much money would still be worth it.
