Ernie: [Hi, Bert.]
Bert: [Oh. Hi, Ernie. Hey, I've been sitting here trying to think of what we can do with this here, letter "L".]
Ernie: [Oh. Well, let's see. You know one thing, you can sing sort of a "La La La" song with the letter "L".]
Bert: [Uh, what do you mean?]
Ernie: [Well, there are all kinds of pretty words that begin with "L".] (Music starts.) [You know, you can sing a few "La La La's" and some pretty words, and you'd have a nice little song.]
Bert: ["La La La," like that?]
Ernie: [Sure. Go ahead. Try it.]
Bert: [O.K. Let's see, uh,..]
La, la, la, la . . . lemon
La, la, la, la, light bulb
Ernie: [Uh-huh.]
Bert: La, la, la, la, lamp post [This is fun.]
La, la, la, la, lump in my oatmeal
Ernie: [Well, that's not quite what I was thinking about, Bert.]
Bert: [No?]
Ernie: [I mean there are a lot of pretty "L" words, and I was sort of thinking of the ones that are more lilting and lovely. You know like...]
La, la, la, la, laughter
Bert: [Oh, yeah. I see.]
Ernie: La, la, la, la, lullaby
Bert: [Oh, like that. Huh?]
Ernie: La, la, la, la, lollypop
Bert: [Ahhhhhh!]
Ernie: La, la, la, la, lights in the sky.
Bert: [Oh! Oh! Ernie, I've got a GREAT "L" word! This is a beauty. Oh, listen to this.]
La, la, la, LINOLEUM!
Ernie: [Ah, no, Bert, uh..]
Listen to me
'Cause "L" is such a lovely letter
For words like "licorice" and "lace"
The letter "L" lights up your face
So why not la, la, la, la, laaaaaaaaaaaaah...
Bert: La, la, la, la, laaaaaaah
Ernie: ...with me?
(Bert laughs.)
