My sister's ex-husband got bit by a brown recluse, once... Yeah.. Just gonna say disgustingly nasty on that one. It's easy to look at a picture... Another thing to be a few inches away from the wound.
I don't really see anything that bugs do as all *really* that terrifying (yeah, trust me, I never want to encounter any of those, ever), since its just their natural evolution to be nasty suckers that wanna live... What really disturbs me is people put jackets on full of bullet ants. To prove their badass. Yeah... Maybe it's because I'm a girl, but that seems like an idiotic way to prove you're manly.
Brain over brawn, baby.
