The Flintstones, Season 4 (1963)

Ann-Margrock:
[singing] You are still awake, and it's half past your bedtime. That sandman had a date he couldn't keep. But when the lambs commence to jump across the fence, I'll count them all until you fall asleep. The first little lamb jumped over the fence and was off to the land of nod. The second and the 3rd were close behind, like 3 little peas in a pod. The 4th little lamb was to chubby to jump. He crawled under instead. The 5th little lamb wasn't there at all. He must've stayed home in bed. Number 6 jumped around as confused as can be. He didn't know where he had been. He jumped over, that's true, but before he was through, he jumped over, jumped back, then jumped over again. The next little lamb was the littlest lamb. Too little for such a big leap. Though she tried like a stout, she soon tuckered out and the littlest lamb went to sleep. The littlest lamb is asleep.
