The spoon does not exist, or something like that...

Actually, there is a way to get your very own Ruby weapon in underwear. This is slightly off-topic, but...

In FFVI, there is a man in front of the fanatic's tower who offers to tell you a secret if you pay him 100000 (i quess that is proper amount of money). Only in SNES version. Pay him the money. Go to map and return. talk to him again. He will offer to tell you another secret for another 100K GP. Pay him the money. He will say a serie of numbers
(e. g. 5-845-2782-678-1) This changes in every time you play the game. Go away and to your airship. As in our example, head north from the top of Fanatics tower and tap the A button 5 times. Then turn to east and tap the same button 845 times etc. When you get all steps done, land, get off and press A button heading north.
When you get there, PM me and I'll tell you more.
