All a Bir-r-r-rd (1950)

All a Bir-r-r-d is a Warner Bros. Looney Tunes cartoon featuring Tweety, Sylvester and an unnamed bulldog, who would later became known as Hector the Bulldog. Produced in 1949 and first presented in 1950, it was written by Tedd Pierce and directed by Isadore "Friz" Freleng, with most voice characterizations courtesy of Mel Blanc (Bea Benaderet does a brief voice-over of Tweety's owner). The title is an adaptation of the familiar train conductor's call, "All aboard!" The instrumental theme used to underscore the motion of the train is "On the 5:15".
