What makes for a great prank call? When the other people believe what it is you are trying to tell them. Think about the funniest prank calls you've ever heard. Hint: They probably didn't begin with "Is your refrigerator running?"
This is pretty rudimentary, but a classic.
Call someone up once or twice a day as different people, each person asking for the same person. Example: Person 1: Is Tim there?
The Mark: No... There is no tom here.
Person 1: Can You just tell him, Rob called?
*Click*
Person 2: (With an accent) Is Timothy there?
The Mark: No, No tim here.
Person 2: Well, if he is, just let him know I'm looking for him.
After about a week of this, call up as Tim, and let the fun begin.
Sure you can call people and say funny things; so can one hundred thousand other people. But what if you could have people call you to say funny things to?! Enter: Call Forwarding.
Ever had a girl be a total whore to you? How about that guy cock blocking you asking for your phone number so he can come to your party tomorrow? These people deserve a special kind of punishment.
Enter: Call Forwarding.

I'll let you come up with some more advanced evil tactics but consider the following:
You borrow someone's phone under the pretense of giving them your number. You type in: *72 + Your Number, and hit send. Now, every call that they get, will come directly to you. Better evn, with Fake Caller ID services like SpoofCard, you can CALL BACK from the very number you are spoofing. Talk about total impersonation ... Very tricky tricky.
If you're just doing regular prank calls from domestic residence to another you can dial *67 to hide your phone number. This is a FREE service that is put in place to encourage privacy in the telephone system. Conversely, when you're NOT making crank calls, someone might tell you to dial *82. *82 is to DISABLE your privacy and show the number you're calling from to the recipient. If you like making funny phone calls, STAY AWAY FROM *82 like the plague. Even though *67 is usually pretty effective, it is only a superficial means of hiding your identity. If you really want to hide your identity, of even change it, you need a service like SpoofCard which is like .06c / minute. (A small price to pay...)
