I have a few nominations after thinking back over some of the "manners". It's not all boys!! I want to nominate Mitzi - seems I recall her getting caught red handed eating meowmies cereal right out of the bowl! She may be itsy bitsy and cute as a button but I think she has a NAWTEE side Another NAWTEE girl is Maggie Sue (sorry, Bob, I HAD to do this!) - she swats her brothers just because she can!! And, she makes sweet Pete run from his supper!! THAT is NAWTEE!!! Stubby draws blood but is too far too classy to be nawtee, besides, she is Dylan's sweetie and so I cannot nominate her.
For a boy - I also have two- Sirrahsim's Boomer and Abner. That cute face with the white streak hides MISCHIEF. And I hear all about Boomer's NAWTEE episodes!!
