Prank Calling...?

Question

I need help to make up a really funny (original) prank call for my friend. What should we say. (we are two girls)

Answer 1

Call you friend without blocking the number and say "hey who is this" is a different voice she will say her name and then say "oh i found this phone on a bench and I was calling everyone in the contacts." She will thing someone found you phone. I do it and it is awesome.
