I’m not a fan of pranks that humiliate or hurt people. They’re just cruel. However, pranks which are harmless and laced with nothing but humor are fine.

This video shows a fine example of the genre being carried out. No one gets hurt, and though several looked a bit freaked out they’ll get over it quickly.

This prank is actually really simple. It just requires an iPhone or other camera-capable smartphone, and the preparation time to take a real photo in advance.

Some of the reactions the invisible friend who suddenly appears from nowhere gets are priceless. So much so I’m tempted to try this out for myself.
