Just have your GF make a wish for a pair of x-wings. Or that you both have super powers. Or whatever. She would be a new customer and this able to make 1 wish.
Edit: Wait... Did she just poof into existence or was she already in line? I've seen this comic so many times and only now am I noticing the girl is in the first panel.
She was poofed into existence one hour in the past, and started walking toward the well. At first it was just a zombie shuffle, mindless and jagged. But slowly and surely, she remembered her made-up past, forgot that she had materialized from thin air.
Perhaps everything we do is the preamble to some future dingbat’s wish. Maybe all of history is unavoidably conspiring to lead to a truck of cash toppling over in front of him, after which point we’ll all blink and look around, dazed, unsure what to do.
