Information is the best revenge. It's legal, it's unlikely to get you arrested or marked as a terrorist, and it's even harder to get rid of than stinky powder.
I suggest sending GOATSE, TUBGIRL, and BREAST RASH.
This resulted in me finding out what the Breast Rash picture was, which has haunted me for days now (there's a link in the comments to the above referenced post if you must know and like me, you'd escaped this little bit of awful meme-age), even though I knew it was fake. not worse than tubgirl, but creepier.
But even I am not cruel enough to inflict tubgirl or breast rash on some anonymous secretary or mailroom clerk at predatory deed company. after attending the Stranger's Hump! festival last weekend and seeing all kinds of things that did not float my boat (but must have appealed to the filmmakers, if no one else) , I've decided the predatory deed people are getting Lemon Party. Who knows, maybe they'll find it an uplifting testimony to the triumph of the human libido over the ravages of age. Or not.
If you are unaware:
http://www.lemonparty.org/ NOT SAFE FOR WORK, duh. has sound for some reason.
the other thing that reminded me of lemon party was this bizarre fake commercial Paul sent me the other day:
http://www.top10virals.com/viralvideos/lemon-party.html (mostly safe for work, but in poor taste. requires sound)
Feel free to steal this idea when you get objectionable mail with postage reply envelopes. I'd love to see a snail mail meme of unsavory direct mail people across the country getting Lemon Party in their return envelopes.
