I recently read that Nikki Cox was once on Mama's Family. Do you know which episode?

According to imdb.com, she appeared in a 1987 episode titled 'The Sins of the Mother.' She played "Little Iola Boyland".

I saw that episode. Although was little, you could tell that it was her. Imagine her playing little Iola Boylen.

I don't know the name of the episdoe but it was in a flashback segemtne when Eucnice went off and got drunk with some friends of her and then showed up at a church sponcered Mother/Dauther show

Oh yeah, I remember that episode... But who's Nikki Cox? I mean, what else is she in?

She played the smart version of Kelly Bundy on that show.
I forfgot the name. Unhappilly ever after thats it.

And her new sitcom "Nikki" was cancelled by WB during the beginning of it's second season.
