I know I said I'm ignoring Kennedy, but I got inspired this afternoon. I'm not wasting my time coming up with my own insults, I'll just use some from the master himself. Blackadder...
(you'll notice my minor editing)


Your brain’s so minute, Kennedy, that if a hungry cannibal cracked your head open, there wouldn’t be enough to cover a small water biscuit.


You are about as much use to me with a hole in your head, an affliction with which you must be familiar, never having had a brain.


A master with all the intellect of a jugged walrus and all the social graces of a potty.


He's got a brain the size of a weasel's wedding tackle.


Your head is as empty as a hermit's address book.


Matt Kenndy: Sorry I'm late.
Edmund: No, don't bother apologizing. I'm sorry you're alive.
