I should have clarified that the things should be nasty creatures. Do you ever get that feeling when you see komodo dragons on the nature show that you would like to rain down destruction on them? DIE MOTHER F*****S That's what I'm talking about.
I like the roach idea. We have the big flying ones.
A shark would be good except I'm in the water a lot and I don't want to think about them any more than I already do.
