Due to many spam and annoying phone callers, the phone has a rather large blocked caller list. The phone starts ring and just as you are about to answer it, the blocked caller screen appears and it ceases it rant. I like to think what happens is that somewhere along the signal, a grey bearded cloaked figure with a staff appears, and slamming his staff on the oncoming signal shouts "you shall not pass". Then signal then dies away and the phone registers call "blocked".
Okay I know that's not how it works, but it would be really cool if what we view as technology and circuitry has a huge vast fantasy world behind it. For example if your computer was actually a city, and when the computer crashes the city is experiencing a hurricane or natural disaster.
