It originally aired on NBC (as separate Parts One and Two, respectively) on March 24 and 31, 1983.  In the "Cheers" pilot, college-educated Diane Chambers was neglected by her previous lover and then hired as a waitress by bartender Sam Malone.  Since then, they flirted and resisted each other throughout the season.  In this two-part episode Sam's more-successful brother Derek becomes Diane's love interest, leaving Diane torn between Derek and Sam.  In the end, Sam and Diane passionately embrace in the office. "Give Me a Ring Sometime" is the first episode of the American situation comedy "Cheers".  Written by Glen and Les Charles and directed by James Burrows, the episode first aired September 30, 1982 on NBC.  The pilot episode introduces the employees of bar Cheers: Sam Malone, Diane Chambers, Coach Ernie Pantusso, and Carla Tortelli; and regular customers Norm Peterson and Cliff Clavin.  In this episode, Diane, brought in by fiancé Sumner Sloan, meets the employees and patrons of the bar.  When she realizes that her fiancé has left her alone in the bar, Diane accepts Sam's offer to be the bar's waitress to start over. Rebecca Howe is a fictional character of the American television sitcom "Cheers", portrayed by Kirstie Alley and created by Glen and Les Charles.

She debuts in the season six episode "Home Is the Sailor" after Shelley Long—who played waitress Diane Chambers—left the show to pursue a movie career.  Much of the show's humor in previous seasons had been based around the interaction and sexual tension between the womanizing, working-class main character, bartender Sam Malone, and the high-class, snobbish Diane.  Rebecca was intended to fill the gap as Sam's new female foil.
