Mistaken for Prank Call

A prank call is a prank call. Except when it isn't.

Phone calls can often be quite tricky things. Because the person on the other end of the line can't see you, it is often necessary to explain who you are and in which situation you are right now. And because of the same reason, the person at the other end has to take your word for it.

But what if your situation is a truly bizzare one? What if it is very hard to convince other people, that Ninja Pirate Zombie Robots really exist, and that a group of them is in your house right now? Or what if you are a celebrity, and the message you want to deliver is: "I want you for my next album/movie/whatever!"?

Well, the persons called will simply refuse to believe you. They will think that you are just a prankster with a sick/unfunny sense of humour. They will either hang up without any further words, or will angrily snark at you, and then hang up.

Can result in an Oh Crap moment if the called persons notice their mistake afterwards, fearing that they may have insulted someone important, or that they screwed up the opportunity to accept an unique offer. Though if they are lucky, the caller will realize what went wrong and try again.
