What is the worst thing you've done to an insect?

[Qwertygiy]

I've only been stung about 3 and a half times in my life. The first time, it was because my dad had shooed away a caterpiller that some yellew jackets were attackeating, and then I forgot about them and it attacked me twice. Then I smacked it in the middle of another sting.

And those "cow killers"? I've heard of them... *shudders* But at least it's not a bullet ant.
