There's been so many episodes that I haven't even read them all, and out of those I have read, it's tough to choose. Anyway, my favorite character is probably White Mage or Black Mage, especially when you put the two together for a hammering effect. My favorite episode is probably the said scene where Black Mage tries to hit on White Mage repeatedly and gets beaten up really badly.

There were other great episodes too, such as Black Mage nuking the forest, and I think there was also one episode where Black Mage got really mad at Fighter for his stupidity and started to chase him all around, swinging his knife. Ouch.
