This hilarious Android app can transform your phone into a whoopee cushion that you can use to prank your friends and family.

At the push of a button, The Whoopee unleashes a barrage of lifelike fart noises. It also has three other modes: motion detector, time delay, and sound detect. Motion detector releases a fart sound whenever somebody sits down, time delay releases a fart sound when you leave the room, and sound detect produces a fart sound when someone speaks.

This app allows you to easily prank anyone. It works really well to break the ice at parties, meetings, and in the classroom.
