Another person has suck-started a rental gun at an indoor shooting range.
That is so uncool.
You freak everybody out, get blood all over somebody else's gun so that it'll be all rusty and pitted when they finally get it back from the evidence locker, and cost the poor small-business owner a bunch of money in lost income.
I know that asking someone who is about to whack themselves to please think of other people is pointless, but think about yourself! You want to make a big dramatic gesture, right? Then do this: First, buy the most expensive gun in the place (it's not like you're planning on paying off the AmEx bill this month anyway, right? Then live a little! Go for something nice, like a Les Baer.) Buy some of the scariest-looking ammunition they have; preferably something with pictures of rappelling ninjas on the box. Now take it home.
Second, write a cryptic Goodbye Cruel World haiku. Bonus points for using mirror writing.
Then, nip off out in the woods by yourself somewhere, put down a drop cloth, lay out some elaborate scene with wax fruit, candles, and those little Fisher Price people, and get on with your business.
I guarantee you will be the talk of the town for months, if not years.
