You know what's more unbelievable though, I just estimated the approximate income for that channel owner. With that subscription base and the average views across all the videos, it translates to about 435K per year. Silly fun, weird way to make a living, although in this case it appears to be a production company rather than a single individual.
On a similar note, Jack Vale is another YouTuber. He invented this device called the pooter http://thepooter.com/ ... he spends his days "working" by filming himself at various stores like Walmart carrying his pooter, makes the fake passing gas sound close to some shoppers, then captures the reactions from these people. Goes home, uploads the videos to YouTube. This is how he makes his living. Apparently enough to comfortably support a somewhat large family. He has 5 kids.
