Found this on Reddit today.  Apparantly you can order bags of shit to be anonymously delivered to whoever you want.   If you’re at a loss for targets they offer some helpful suggestions up on the site:

The TOP TEN reasons to send some one a package of shit:

  1. To your ex-husband/wife/boyfriend/girlfriend
  2. Neighbors pet crapping on your lawn
  3. For your mean boss
  4. For a salesperson or mechanic that ripped you off
  5. A Last minute gift for some one who has everything
  6. A gag gift
  7. For a rich gloating friend, to knock them down a peg
  8. To the teacher that gave your son/daughter a D
  9. Some one left you negative feedback on your auction
  10. You just don’t like them

Send someone a big steaming bag here.
