This is the best prank ever that I played on my friends. Ask your friends to check this [ GHOST PROFILE ] . It will look like a scary ghost profile.But that's not the interesting part here, Ask your friend to click on photos. 

Here come the scary part, Out  of nowhere a ghost face comes out from the centre with a scary shout.

Your Friends shouts-Our prank rocks.

When I tried this prank on my friends few girls even shouted in fear.
