This gives me an idea for an app to make for mobile phones. Leave the phone off or turn it off before you get to the airport Security line then when you turn it on the app auto-starts which makes the phone slowly boot. Then when the phone does finally boot it shows a fake screen showing "Installing update 1 of 44" and make it so it never ends. My password is my index finger I should change it to my middle finger, my password is written down and really complex I'd never be able to remember it without seeing it.
