On the rare occasion when I get really bored, or if I'm seriously procrastinating, I like to read Craigslist. Especially entertaining are the free and barter sections, because you get a nice glimpse of what we do not place value on in this culture. Which is nice for a change. Or, as in this case, you can witness the desperate lengths some people will go to in order to make a buck.
Perhaps this person is joking. Perhaps not. I don't know which scenario is worse.
