The rivalry between As the World Turns’ Kim (Kathryn Hays) and Susan (Marie Masters) was one of the show’s signature feuds and in aninterview with We Love Soaps, Hays looks back on Susan’s ability to get under Kim’s skin.

WE LOVE SOAPS TV: I especially liked how that side of Kim came out of Susan. She was Kim's Achilles heal for patience. No matter how cool and calm Kim tried to be, Susan could always push her buttons.

Kathryn Hays: [Laughs] Oh yes. One of my favorite shows we did was when Chris married Alison. Marie and I had a scene where I went to her house, we were talking about our kids Chris and Ally. Kim was trying to make peace, trying to be reasonable, and Susan was having none of it. We got down to the floor and were getting ready to tape. In rehearsal, Marie had added a line at the end, “Be sure to say hello to Bob for me.” It was a real dig at Kim. At the end of rehearsal it made me so mad, as Kim. I knew what I felt like doing, and I didn’t do it at rehearsal. But I knew that if she said that during the taping that I would was going to let it fly. So we’re taping this thing, it had gone well. Kim was going to the door, and Susan said, “Be sure to hello to Bob for me.” I yelled, “Oh go to hell!” and slammed the door. Apparently in the control room they were hysterical [laughs]. But they left it in the show. I was so glad they did. After they called yelled cut we just laughed so hard.
