For the record, reports say he was fine even though he got hit on the head by a drone. The show even continued normally. 

If a drone headbutts you, pretty sure you get to keep that drone and GoPro.

From the Daily Mail:

It was supposed to provide the perfect festive romantic moment: a mistletoe drone that would get diners at TGI Friday's to kiss on camera.

But the restaurant's plan to lure in festive diners went horribly wrong after one of the machines smashed into a photographer's face at a launch event in New York.

Georgine Benvenuto was left in shock after the machine flew into her face, slicing off the tip of her nose and cutting open a section of her lip.

The ten-inch drone became so entangled in Miss Benvenuto's hair that she even feared she would lose an eye.
