Unimpressed Dog Tells Humans: 'Blah, Blah, Blah'

This dog has just about had it with all those silly humans who keep trying to talk to it. Don't they know he doesn't speak English? Or any other human language? But wait, if that's true why does this dog respond by saying, "blah, blah, blah"?

At least, that's what it sounds like the dog is saying. He's clearly not impressed with the conversation!
