The 10 Funniest Prank Calls from Prankdial.com

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.
