The only thing I'd personally kill would be to boil a lobster.
Of course, then there's the bleeding hearts who say that it's cruel to boil a lobster alive and you should put it in warm water and gradually heat it up so that it falls asleep.
blah... at that price, I say it's my right to take the lobster, hold it over the boiling water for a second to let it see what's coming, fake it out a few times just for fun, then throw it in.
