Many people use their smartphone all the time, so one of the best ways to mess with them on April Fools' Day is to mess with their smartphone.

Use a mannequin head and place it next to your partner while they sleep. Wake them up and as they try to look at you they freak out as they see the fake head.

For this April Fools' Day prank you need to get up early or stay up late. While everyone's asleep move the car around the block. It appears stolen!
