Even in death, Steve Irwin is more of a bad motherfucker than you'll ever be

getting stabbed in the heart survival rate 1-2% chance

getting stabbed in the heart with a barb covered in poison that effect your circulatory system 0-.01%

(numbers are made up to make a point so dont anyone try to bitch about them)
make more sense?

Im sure he did. And the knee jerk reaction you are talking about, is a stretch reflex. Not a getting stabbed in the heart reflex.

Either you are a retard or just trying to sound cool, in which case you are still a retard.

knee jerk reaction = reference to anything you just do without thinking about it. aka getting stabbed with something, your first reaction is to just pull it out.
