Directed by: Burt Gillett
Starring: Billy Bletcher, Pinto Colvig, Dorothy Compton, Mary Moder
Continuity mistake: When the two pigs hide from the wolf in the stick house, the door has a white knob with a backplate. When the wolf blows down the house, the backplate has vanished from the door. In the next shot, the backplate reappears, and the knob has changed to black. In the shot after that, it's back to a white knob with no backplate. (00:05:03 - 00:05:30)
Fifer Pig, Fiddler Pig: Who's there?
Wolf: I'm a poor little sheep with no place to sleep. Please open the door and let me in.
Fifer Pig, Fiddler Pig: Not by the hair on our chinny-chin-chin. You can't fool us with that old sheepskin.
