I was talking to my buddy and playing FF6A while not paying attention and repeatedly hitting 'a' during battle. I glance at my screen after a few seconds and I see large summons popping up on my screen and it took me a second to realize it was Crusader. My friend said he saw my jaw literally drop and asked me wtf was up. I told him I just saw the strongest summon on my screen wipe out my party while I was still in Narshe at the WOB. Of course that meant absolutely nothing to him (he doesn't play FF OMG LOSER) but it made me happy that a game I've been playing since my childhood can still surprise me. I'm just happy I saved a few minutes before this surprise....
I forgot to mention this obviously occured through Setzer's slot technique. After reading online I see it was triple bar that summons a random esper? I guess I haven't used Setzer enough to experience that, or I did at one point and just completely forgot =D
