Voice actors that if present play many characters
So your enjoying the latest installment in some animated series when you get a severe case of Hey, It's That Voice!. Then several minutes later you get it again but with a different charcter. Eventually it can get to the point that the voice actor is having an involved conversation with himself but one has Just a Stupid Accent. Basically the Mc Neil Clause is "If X is in this then he will most likely play multiple to half the cast." Named for VA Scott Mc Neil, who one can only assume has this in all of his voice acting contracts.
