Planet Nelson points us to getmooh.com, an automated service designed to help you escape a variety of situation by "…calling you automatically on your phone at a pre-specified time and playing you a recording which will either instruct you on what to say to elude your tormentor(s), or which will simply give a convincing sense of you being on an important call."
Wouldn't this make a great iPhone app? Simply program the phone to call at specified time… or you could simply reach in your pocket, press a button … and get the call 5 min later
I believe this iPhone app exists. My cousin was telling me about it this weekend.
The same cousin, incidentally, has a cool iPhone app that makes your friend think he’s accidentally broken it by a) pressing the glass too hard and breaking it, b) overheating it so the screen melts, or c) accidentally pressing the wrong button and deleting all your information.
