Quote from Cliff in The Improbable Dream (Part 1)
Sam: OK, one more thing here. What do you think is going to make her go to sleep faster, Brahms's "Lullaby" or "The Sounds of Spring Showers in a Rain Forest"? Cliff: You know, Sammy, that question has plagued mankind since the beginning of time. How to lure to our bed the elusive Morpheus, son of Hypnos, known to the sand dwellers of Rome as Somnus. Now... Norm: If you really want to put her to sleep, Sam, record him.
