Parents Pull a Doorway Prank on Their Kid
I am NOT a big fan of pranks/videos in which parents really scare the crap out of their kids. To me, that's just mean, and a bit cruel. This prank, on the other hand, is pretty funny. It's innocent, nobody gets hurt, and the kid's reaction is pretty funny.
The concept is pretty simple. Put a bunch of clear plastic wrap in the kid's doorway...and then make him go to his room for whatever reason. I think you'll get a kick out of the 'ugh' that comes out of the victim.
