Dee Thomas (Danielle Spencer) is Raj's younger sibling. In the show's first season she is irksome and rude, and says things that are well beyond her years. She is shrewd and obsessed with making money, usually by blackmailing her brother and his friends a quarter at a time. As the series progressed and Dee grew older, her caustic personality mellowed into a sly sense of sarcasm, which included continuous insults of Rerun based on his weight and his stupidity, and she became more likable and clashed less with Raj. After Raj moved into an apartment in the third season, Dee remained in the Thomas house with Shirley moving in to help out. Her trademark phrase is "Ooooohh, I'm tellin' Mama!" or "Ooooohh, you're gonna get it!" when she witnesses or hears about a wrongdoing, especially by her brother. Her favorite food is peanut butter. Her birthday is September 17.
