the difference between a weapon and a tool

What’s happenin’, captain, when you feelin’ low?
you said, you didn't believe how evil people can be
until you’d seen it for yourself—
you know cutting someone’s head clean off
isn’t an easy task, though easier
the second time around. but that was then—
yesterday, you bought a chainsaw,
twenty-inch, from Home Depot, good deal,
fits all your batteries,
any cord you’ve got will work.
a bargain—lifetime guarantee.
just what you need.
be here Sunday.
isn't that nice?
