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.

This is a great joke to trick your colleagues and this one is deviously simple. You only need a piece of tape.

This practical joke is plain and simple, thus perfect for rookie April Foolers. Put some tape under the water tap. When they turn it on, water squirts everywhere.
