This guy and my puppy dog would be the best of friends.
My dog has not one, but two, large, nigh-indestructible squeaky toys, with not one, but two, squeakers in each one.
This guy has one tiny squeaker hidden his mouth that makes odd, high-pitched sounds when air is applied to it.
It's like these unsuspecting passers-by were subject to one human-sized squeaky toy, only they didn't quite know where it was coming from.
And if that wasn't enough, the guy tells you at the end of his prank video where you can buy your own personal squeaker...which, now that I think about it, might be a good way to have a little fun with my dog.
