Description:  "It's the Wolf!" is a Hanna-Barbera cartoon segment about the wolf Mildew's constant attempts to catch and eat a lamb named Lambsy. Mildew's plans are always foiled by the sheepdog Bristle Hound, who intervenes after Lambsy cries out, "It's the wool-uff!". The humor comes from Mildew's disguises and the predictable cycle of his failed schemes.

The plot: A wolf named Mildew Wolf, voiced by Paul Lynde, tries to catch a lamb named Lambsy Divey.

The catchphrase: Lambsy would shout, "It's the wool-uff! It's the wool-uff!" to warn others.

The protector: This alarm would summon Bristle Hound, a sheepdog who would use his shepherd's crook to throw Mildew over the horizon.
