Lulu Gets the Birdie (1944)

Mamsie catches Lulu making a mess of the kitchen, so she punishes Lulu. When Lulu asks, "How do you know that I made this mess?", the maid says sarcastically, "A little bird told me!" Angered that the bird outside her home snitched to the family's maid, Lulu goes after the bird with her slingshot.
