While I have met a lot of ignorant humans in my time who just babble on incessantly, I think dogs still win here. At least mine do when they do things like jump up off of their beds, bark at the wall for a minute, then lie back down, go to sleep, and have a dream about barking- which I know because they make little tiny bark noises without opening their mouths.
Reminded of the time a recruiter asks Porky Pig to give his name. He can’t hear it through the stuttering, so he has him write it out. Porky continues, writing out his stutters.
