There's one at the Moogle's Gift stables in bentbranch that had me absolutely rolling. i tried to screenshot but my computer decided to be a ra-tard. I believe it was the owner of the place and post-lvl 30. If anyone knows to what I'm referring, please post it. It's driving me crazy that i cant remember!

As for one that I remember, there's a Mi'qote wood wailer in the North Shroud, whose name escapes me, that constantly replaces the word "now" with "meow". I find it hilarious personally because in my troop (US Army) we make fun of anyone who says "Time: Now" by saying "right meow" and "time: meow". More funny to those of us in the unit, but all the same i found it hilarious
