Great Final Jeopardy question on St. Valentines Day.

Broadway Plays
Rita Moreno and Sally Struthers were the first to star in the female version of this comedy. Their characters became Florence and Olive.

What is the Odd Couple

I remember a Sally Struthers interview when asked who she disliked the most working with she brought up this play's co-star. During the interview she was so sweet she wouldn't give the name. I had to research it and found it was Rita Moreno. RM treated SS like dirt. The stories SS told were unbelievable how big of a b*$#@ RM was.
