Roseanne guested on The Nanny in episode #5.1 -
"The Morning After."

This episode appeared in the fifth season and aired on October 1, 1997.

Roseanne played the part of Fran's cousin, Sheila, an interior designer, who is hired by Fran to redecorate the kitchen. An idea of Maxwell's as a way to redirect Fran from what happened to them in season 4's hospital bed kiss/grope.

I loved the goings-on that happened in that kitchen soon after. From Maxwell's, "Miss Very-Fine" to Niles' low throated, "Toriello... lookin' gooood.".
