Coudal.com has perhaps the most useful PDF file of the year available to download…

Do you ever get tired of those idiot people who suck up all the ambient quiet while talking on their cell phones about things that they – well – should probably just keep quiet?

Take action now:

“After reading a story in the NYT, Jim's wife Heidi decided that maybe there was a way to fight back against the obnoxious cell phone users that we all have to deal with in stores, restaurants, trains and pretty much everywhere else. Can design ride to the rescue? Jim and the incomparable Aaron Draplin think it can. So, as a public service, we introduce the reasonably polite SHHH, the Society for HandHeld Hushing.”

Download this PDF, get out your exacto knife or scissors, and start fighting back (NOTE: The PDF contains a few choice profanities, so if you’re easilly offended, don’t click).
