At Bethla Garrison's Sluice, have you ever tried placing some of your units at the front of the damn before Ramza pulls the switches? It's hilarious watching the water engulf your units and then not seem there after the water stops flowing out of the damn. When I go back to my formation, I'm like "Hey! How did you all get back so fast?!"
This one may not be funny to some people, but whenever Cloud's Finish Touch adds dead, I like to say, "Heh heh, it didn't do any damage; it just killed the enemy."
