Do you know what Sunday is? Besides being Apple's 36th birthday, it's April Fools Day. The one day out of the year when you're allowed to play a prank on your friends without fearing for your physical well-being. If you're like us, you're already plotting and planning. If you're not, well, don't worry—we have a suggestion: prank calls. We're not talking about the old school "Is your refrigerator running?" jokes. Nah, we're talking about spoofs that may cause a rift between you and one of your boys.

To get your creative juices flowing, we decided to look through the submissions archives at Prankdial.com, a site and mobile app that allows you to send pre-recorded messages—complete with pauses—to your friends, and see what kind of hilarity we could find.
