1 Death of Insanely Overpowered Fireballs: HOW DO I GET A PASSPORT?
1 Disinterested Receptionist: Oh, I can do that for you.
1 Death of Insanely Overpowered Fireballs: AH! ONE PASSPORT, PLEASE.
2 Disinterested Receptionist: Here’s the application form. You need two photos of your face.
3 Disinterested Receptionist: Stand in front of a plain, featureless background.
3 Death of Insanely Overpowered Fireballs: OKAY, EASY.
4 Disinterested Receptionist: You’re not allowed to smile.
4 Death of Insanely Overpowered Fireballs: THAT MIGHT BE A PROBLEM.

I've second guessed myself with the punchline setup on this one. I originally had simply "You're not allowed to smile". But it bothered me that perhaps some people might not work out what the joke was. So I added the "or grin" part.

I'm still debating in my head whether it would have been better to leave it...

Well, I decided to change it back, as you can see. Hopefully the above paragraphs make a bit more sense now.
