any time black mage shuts an idiot up, which is alot of the time.

or where his efforts just fail (ketchup packets was priceless)

One of my very favorites has to be this
"They're made from baby skin. Fresh daily."

The other would have to be where BM uses his "Laser Eye Beams" or where BM is wounded and RM yells something like "Yes! He is wounded! Strike down the monstrosity before it can recover!" I can't remember which comics those where though.

ok as disturbing as that comic was, I got to admit, it made me laugh too.
Fighter is King Steve's long lost son I think, it's the only reasonable conclusion.

My favorite comic is probably Episode 676: Supernatural Selection
where Red Mage shows off the monstrosity that was a chocobo.

My favorite is when they were telling stories around the campfire, and BM scared everyone except Fighter and WM by having the story end in massacre.

I can think of a far worse nightmare.

The best, by far, is when WM tries to revive BB with part of his head missing and his head explodes. I can't find that episode, so if anyone could help me out...
