This Windows 8 app made me smile. Open the app and touch an icon and your PC plays a recording that sounds like you have an emergency in your house, giving you the opportunity to politely hang up on a telemarketer or other annoying-but-difficult-to-get-rid-of caller.

Sounds include Doorbell, Crying Baby, Gunshot, and CSI, which plays a voice saying "Get off the phone. We need to clean the blood out of the carpet." That last one is my favourite.
