Finally, someone who isn't going around chatting with random people. I can even excuse the lack of compass directions for this.

I took out my map and teleported to New Super Uber Ultra Megatropolis. Suddenly feeling decisive, I quickly formulated a plan. "Faw, Araches and L33tz4n, go back to the academy to research the spell. Shuri, stay with me."
As all my team's mages ran off, looking slightly surprised, I took out the stamp. I cut everything but the Fooruman head off with my teeth, and after chewing on the scraps for a while, bit in serrated edges. I ran off to the stamp man, and presented him my 'stamp'.
"This is the rare and powerful Fooruman stamp! Only one was ever made!"
"Wow, that's rare! ...why is it so wet?"
I looked at the stamp. Maybe using my mouth to cut the stamp out wasn't that good idea. Still, I was on a roll.
"I recovered it from a SHIPWRECK."
"How could it be wet, then? The sea is frozen."
"It was a shipwreck... IN THE SKY!"
"Oh. Okay. Well, for an item so unique as this, I'll give you ten billion dollars. No more, no less. Deal?"
