Oh! A paperclip sign. That's ingenious. I didn't realize there was a meetup last time so wasn't there either, but I'm very excited for this one.
For paranoid debating, perhaps the volume of Nutella consumed by France last year, or if that seems difficult to verify, maybe the area of cornfields in Wyoming or the height of some moderately famous tall building somewhere.
I'll be there again, hopefully, unless last-minute homework is assigned.
