When I was a kid, my parrents did simmilar. But... A few boxes later, the gift I wanted was there. It made the surprise all that much better. If that is what these folks did, the joke was carried too far.
In the same tradition, but done much kinder, they got me good a few years later. I had been learning to ski at my local mini-slope. I wanted my own skis so I wouldn't have to rent. We didnt' have a lot of money, it was the early 80's, most people didn't. Mom and Dad compromissed and said I could get my own boots. So me and dad went to the sporting goods store, tried on boots and picked a pair out. While we were there, just for fun, we checked out skis and poles.
Under the tree that year was a huge box and I knew I got my boots. It was the first box I opened, I wore them while we opened gifts. (I was all of 12 Y/O) Sometime in the middle of opening stuff, mom says "help your dad with that." I turn around to see him holding Skis w/bindings and Poles. Complete surprise and the best christmas ever.
I'm going to give those folk in the video the benifit of the doubt and assume the kid got his x-box @ 5 minutes after the clip ended.
