family guy episode where peter gets a vasectomy
Sibling Rivalry (Family Guy) "Sibling Rivalry" is the 22nd episode of the fourth season of the animated comedy series Family Guy. It originally aired on Fox in the United States on March 26, 2006.[1] The episode follows Stewie as he battles with his half-brother, Bertram (voiced by Wallace Shawn), who is born to two lesbians after Peter donates sperm. Meanwhile, Lois begins excessive eating after Peter undergoes a vasectomy and loses his interest in sex.[2]
Family Guy The family was conceived by MacFarlane after developing two animated films, The Life of Larry and Larry & Steve. MacFarlane redesigned the films' protagonist, Larry, and his dog, Steve, and renamed them Peter and Brian, respectively. MacFarlane pitched a seven-minute pilot to Fox in 1998, and the show was greenlit and began production. Shortly after the third season of Family Guy had aired in 2002, Fox canceled the series with one episode left unaired. Adult Swim aired that episode in 2003, finishing the series' original run. However, favorable DVD sales and high ratings for syndicated reruns on Adult Swim convinced the network to renew the show in 2004 for a fourth season, which began airing on May 1, 2005.
