My wild prank idea is to have someone disguise themselves as a crazy, drunk and wild, pregnant old lady, and she should be having dinner at a restaraunt or buying lunch somewhere at a cafe. Then while she's ordering her food or sitting at her table just about to leave, her water should braeak and she should totally be unaware of what just happened. Then when people start to notice that her water just broke and there's fluids all around her, she should say that she's perfectly fine and has the situation under control. She should maybe even start cursing and getting really offensive. Then she should start to walk away crossing the the street and a fake newborn baby should fall out from under her dress. It should be a still birth of course because it would be too hard to imitate a live newborn baby. Then to make it even more shocking and hilarious a dogwalker should walk by and the dogs should try to eat the newborn baby and start barking at it and biting it. Then the old lady, drunk and wild, should be puffing on a cigarrette on the phone completely unaware that there's a newborn baby dangeling from inbetween her legs. Then she shouldget into her car while she's cursing at the dogs following her and slam the door so the umbillical cord will snap. Then she should totally drive off and leave the newborn baby for the dogs to chew on. Everyones jaws should be dropped to the floor from the whole scene the wild old lady just caused.
