question: Who did Meg's voice on the original pilot of Family Guy?
short_answers: Rachael MacFarlane
context: On the season 1 DVD commentary for the "Drawn Together" episode "Hot Tub", Cree Summer claims she was offered the role to play Meg but was dismissed by the producers. Meg was voiced by an uncredited Lacey Chabert for the first season, and by Mila Kunis in subsequent seasons after Chabert became busy with school (at the time) and her role on "Party of Five", although some of her work became second season episodes due to production order. Mila Kunis won the role after auditions and a slight rewrite of the character, in part due to her performance on "That '70s Show". MacFarlane called Kunis back after her first audition, instructing her to speak more slowly, and then told her to come back another time and enunciate more. Once she claimed that she had it under control, MacFarlane hired her. MacFarlane stated that Kunis "had a very natural quality to Meg" and she's "in a lot of ways [...] almost more right for the character". Kunis's voice is first heard as Meg in Episode 3 of season two "Da Boom", and the voices switch back and forth in the broadcast order until settling on Kunis. Tara Strong provides Meg's singing voice in "Don't Make Me Over".
