You made think of four characters:
-Jill Smith, whom everyone seemed to hate because she was an even bigger liar than Rachel (who seemed to have a reason for being so messed up, considering her past and home life);
-Paul Hanley, who was described by somebody around here as "a sadist who's too cowardly to do anything" and who just can't make a simple statement without monologuing;
-Lew Miles, who was always going, "I have to tell you something!" "I can't tell you!" "I have to tell you something!" "I can't tell you!" "I have to tell you something!" "I can't tell you!";
-and finally, Betty Anderson herself from the show's infant days, where she kept on telling Rod, "I gotta
talk to you! I gotta
talk to you! I gotta
taaaaaaalk to yoooooou!" whereas in the book, Betty simply walked up to him and told him, with all the frankness in the world, "I'm pregnant. We gotta get married."
