gollark: Oh, Sans from the Undertale movie? That makes sense.

gollark: Of course, if I were you, I would have predicted that issue and produced a fake list as a bluff. Since by the seventh gollarious axiom you may be me at any time, you did, so I have to ignore that, since it contains no useful information.

gollark: Indeed.

gollark: It's not 1 in 11. If I have my own ideas for which is which and they roughly align with yours, I can leverage that to approximately *find* yours.

gollark: Surely you can just line up the gap in it and find out where you are.
