(Clearly you need more FMA icons in general! *helpful* This one, I will not comment on relevance.)

Yes absolutely. And as we have discussed, it would be grindingly horrible without the ridiculous humor and the lighthearted bits, but that doesn't mean the writers ever forget about the underlying themes when they scurry off into pandas and shonen fight scenes and insulting Ed's height. Which I really appreciate. It's the right kind of mood whiplash, for me, because it's not really whiplash, and it's not quite gallows humor either.
