Mailboxers
You know how your mailbox is constantly under attack from hoodlums, ruffians, hooligans, ne'er-do-wells, and even terrorists? Now there's an answer. Via boingboing, Mailboxers come in 3 flavors: "The Stinker" applies a smelly skunk oil onto the bat of vandals, which they will hopefully transfer to their brand new upholstery; "The BatGrabber" deploys a hidden nail system to grab the bat right out of the criminal's hand as his car drives on!; "The Tattler" is an alarm system that alerts those inside whenever the mailbox has been opened. All very afforadable (and attractive!)
