The writers do write things properly at times. :) When Penny's mother first opend up the door, she lokked way too young to be her mother. People were probably saying, "Is that the aunt she was talking about? or is that her sister? That woman looks way too young to be her mother.:confused: Then, Ms Gordon says, ""I had Penny at 16 years old." And then it becomes clear why she looks so young.:)

Ray calls Willona, "Willie,", in Willona's Surprise. Willona later says in an unrelated episode, "My ex-husband used to call me, 'Willie.", :) They got that one right too.:)
