I just love it when they say "how can you do that?" I get a real serious look and then say "It's actually quite simple I use a 63 pound bow to propell a 40 grain arrow tipped with a razor sharp head. I generally aim for both lungs where the razor sharp blades puncture both lungs causing a bilateral pnuemothorax and subsequent death within 30-60 seconds"

It generally takes them just a little while to absorb what I said and they usually shut up and walk away. Since there's no real reasoning with the type that asks that question in the first place, I try to have fun with it. If they say anything else, I simply tell them that the only difference between them and me is that they hire a hit man to kill their food. If they declare that they're vegetarian or vegan, I offer them a steak!
