Six-month-old babies in TV ads who speak English like 35-year-old Harvard MBA graduates?
Dogs and other animals that can speak English as well (or as poorly) as your typically addled teenager next door?
(Or lizards that can dance?)
I’d rather see humans’ barking than dogs’ speaking English, or grown adults’ "mewling and puking" like infants rather than infants’ peorating about consumer products. At least it would more accurately depict the human condition.
