Normally, the junk mail I receive goes straight into the garbage, but I couldn't easily dispose of the subscription offer I got last Friday for "The National Review". Exactly how I got on this mailing list, I'll never know. It did remind me of a method employed by my former roommate to deal with such unwanted garbage.
Take everything but the postage paid envelope and shred it. Then you stuff the shreds into the postage paid envelope, seal it and mail it back to them. That way they have to pay postage twice. I'm sure these folks couldn't care less, but it's at least somewhat therapeutic.
Now, if only I could get a hold of some cheap, heavy lead slugs that would fit into a #10 envelope.
