The latest stunt from YouTube prankster Roman Atwood features him pretending to throw his child over the second-floor banister while the boy's mother watches in terror.
It begins with Atwood playing with his son, who is dressed in a Spiderman costume covering his face, on the upper level of a large home.
They are greeted by the boy's mother, who is then sent downstairs as a ploy, allowing them to set up the prank. Atwood substitutes his son for a dummy, which he tosses over the railing.
His wife screams in horror as she sees the boy falling to the ground below, lying motionless as soon as he hits the floor.
Watch her reaction in the video above.
