Your rhetorical skills are quite impressive, sir.
However, your powers of observation seem to be a bit lacking: your "silly little brain" is not silly at all -- it melts brains! and can rebuke undead, to boot. And never mind that it is just a brain -- without a body -- this brain refuses to die! And with 3 whole HD, no less -- A 3 HD BRAIN!
Now, if you want to see silly, simply flip a few more pages to the "desiccator". This guy's major attack is ....... (wait for it) ....... (wait for it) .... hali-fucking-tosis. Really? "Oh, wait a minute -- I need a drink of water" -- give me a break.
