I can think of a few that I liked.The Yak,where an invisible narrator talks about the cartoon yak being displayed in the segment itself.At the end of the segment ,the narrator says to the yak"You're not an ordinary yak you know.You're a yakkity yakkity yak yak."Insulted the yak ferociously runs right into the screen,and we hear a loud crash and stars go flying.Another was a musical cartoon involving a goat who is teased by a dog,a cat and I forget what the third character was.Each time this goat gets teased,he gets"MAAAAAAAAD".The third one I can think of off hand,was a cartoon painter(Leonardo DaVinci in cartoon form perhaps)with the famous Mona Lisa painting,who says"P Painting".Then Mona Lisa is suddenly brought to life,when she snatches the painter's paints and paint brush,and paints a picture frame around the top half of him.She then snatches his torso and walks out of her own picture.
