Everyone can enjoy a good prank, especially when the joke isn't on them! Here's one that you have to watch because it is so funny.A guy dresses up as an old granny and gets unsuspecting people to help him/her with a wireless speaker in order for granny to listen to some music.

Most people that offered to help, figured the older lady would probably be listening to the old standards or classical music, but were they in for a surprise!

See what happens in the video below.
