With the tentacle, you could Mike from College Roomies from Hell (assuming they had one in blue).

The TSA website indicates that all cell phones, and most laptops are under the 8 gram limit for lithium-ion.

What is interesting to note, is that the only batteries that can go in luggage are those that are installed in a device (not a spare). Also, you can have only up to two batteries (spare or installed) in your carry-on luggage that have a total of 8 to 25 grams of lithium. That means, if you have a laptop with a spare battery, you are OK. If you have a the laptop with spare, you can't have your cell phone (that would be three batteries), and heaven help you if you bring your camera.

The real kicker, is that the devices must be turned off at all times. You can't use your laptop, iPod and such on the plane. Sorry, but no tunes for you, bring a book!
