If it's not Bonsai Kittens... Kittens grown in jars... then it's the Tiger looking after the piglets dressed as tiger cubs, both of which are false. Look them up on wikipedia and please don't spread them to others via e-mails.
Another load of bunk I found while hitting stumble today were these gems of false-isity from: Cell Phone Tricks
2. Lock Your Keys in the Car? - If your car has a remote lock/unlock device (and you have a second one, say at home - aside from the one on your keychain that's locked inside the car) you can call someone at home on their cell phone from your cell phone, hold your phone about a foot from your car door, and have the person at home press the unlock button on the device, holding it near the mobile phone on their end. Your car will unlock. Distance is no object. You could be hundreds of miles away, and if you can reach someone who has the other remote for your car, you can unlock the doors.
False! watch this video here.
4. Disabling a Stolen Phone - To check your mobile phone's serial number, key in the following digits on your phone: * # 0 6 #. A 15-digit serial code will appear on the screen. Write it down and keep it somewhere safe. If your phone gets stolen, you can phone your service provider and give them this code. They will then be able to block your handset so even if the thief changes the SIM card, your phone will be totally useless.
False... Apparently a service does exist for this, but I've had experience with it.
When you find the website for this, there's no way to register your name or serial card. I wrote and complained to the website and got a response days later asking me to give them my details and the number. I did so, but the number still registered as still working. It seems nobody is seriously interested in this idea, it could work, but trust me, it doesn't.
