You may remember this guy from his last viral video, which earned him a gues spot on Jimmy Kimmel. It's tough not to think this is staged–I could pretend like I've watched this 17 times to assure you that it isn't, but that would be a lie. I watched it once. I found it enjoyable, and if it is staged, they do a decent job in masking that. (Though in a huge upset, the YouTube comment mafia seems to think its fake.)
All in all, its a video on the internet and its pretty impressive. The celebrations are also rather funny. Good for this family.
