Not complex but surprising and scary as hell.

A few:
"SCIEEEEEEEENCE!"
"Science for the Science God!"
"I! Hate! Babies!"
"We're gonna F*&^ing die!"

If all else fails, I'll do my best Reb Brown impersonation.

[HEADING=1]DEMACIA!!!!![/HEADING]

Fixed that for you.

As for me, probably something nonsensical and full of ham, like "I'm GONNA MURDER SEVEN KINDS OF SHIT OUT OF YOU, SLANDEROUS FOOL!"
