Son pulls off epic doorbell prank: 'Scan your eye, see if it lets you in!'

If you have a doorbell camera at home, you might want to try this hilarious prank on some unsuspecting guests. A son from Greater Manchester, UK, told his dad to lean into his doorbell camera so that it can scan his eye, as the device was actually a “retina scanner.” Shockingly, the father believed the lie, and tried to scan his way into the house multiple times.
