Putting together a really great prank phone call is hard work; you have to figure out who you're going to call, come up with a scenario, practice the script and come up with an escape plan if things go wrong. Or at least, you used to have to do all that before Kidding Mo, now you can just pick a phone number and a scenario and let the magic happen.
The app lets potential pranksters choose from a number of different scenarios, then customize and fine-tune the whole underhanded affair. The app uses a hidden caller ID so your friends won't know it's you, and all calls are made over the Internet, so no worries about using up your monthly minutes with a bunch of prank calls. The company claims that there's also a way to block your number if you're getting annoyed by Kidding Mo's pranks, but the link they provide seems to only go to the app's Facebook page, so that may be a prank in and of itself. We apologize in advance for giving your friends this brand new way to annoy you.
