The story line was ahead of it’s time, but when Carol and Susan got married on "Friends," network bosses were bracing for huge audience backlash.

One of the show’s co-creators Marta Kauffman says while the wedding between Ross’ ex-wife Carol and her girlfriend was given the green light, big measures were put in place to deal with the fallout.

“When we did the lesbian wedding episode of 'Friends,' everybody was up in arms,” she told The Hollywood Reporter. [NBC] put 104 operators on for fear of getting a million phone calls. They got two. A month later, they got the letters, but nobody called. And the letters were all from the Rev. [Donald] Wildmon. What a putz!”

The showrunner, whose new series "Grace and Frankie" airs on Netflix, also spoke about the endless "Friends" reunion rumors — and gave a pretty definitive answer.

“Oh, oh, don’t even. I don’t know how many ways we can say no,” she said.
