No I haven't, but I know exactly the skit you're talking about. Throughout the clip, we hear a woman's voice singing "milk, mi-ilk, milk", followed by some oboe and (clarinet?) music. At the end of the clip she sings:
"Milk, mi-ilk, milk.
So good and warm and white.
Milk, mi-ilk, milk
makes everything seem right."
If I see it online I'll let you know.
