[Inside the garage of 1216 Franklin Avenue, Lincoln and Clyde stand and watch as Lisa plays the organ Lucy used in "House Music". Her back is to them, her mood ecstatic.]

Lisa:

I thaw three thhipth come thailing in

On Chrithtmath day, On Chrithtmath day

I thaw three thhipth come thailing in

On Chrithtmath day, in the morning

[In the middle of the first verse, Lincoln sticks out his tongue and wiggles his hands on his ears. During the second verse, Clyde pulls the ends of his lips apart and goes cock-eyed. Lincoln starts to slurp on his fingers. The boys then chuckle.]

Lisa:

And what wath in thothe thhipth, all three?

On Chrithtmath day, on Chrithtmath day

And what… [She stops the music and turns to the boys.] Quiet, rubeth!

[The boys stare stone-faced in silence, neither moving a muscle. Then Lisa resumes her playing.]

Lisa:
…wath in thothe thhipth all three

On Chrithtmath day, in the morning?

[As the third verse starts, Lincoln mimics Lisa with exaggerated expression. Clyde stifles a laugh, then he cracks up.]

Lisa:
Our Thavior Chritht and hith lady

On Chrithtmath day, on Chrithtmath day

Our Thavior Chritht and… [She ceases and gives her attention to her audience.] Thilenthe, yokelth!

[The boys cover their mouths. Clyde stifles his laughing.]

Lisa:
…hith lady
On Chrithtmath day, in the morning

[As Lisa goes into the fourth verse, Clyde pulls his cap over his face, while Lincoln flaps his ear flap. The boys manage to emit a quiet giggle. However, it's not silent enough.]

Lisa:
Then let uth all rejoithe amain,
On Chrithtmath day, on Chrithtmath day
Then let… [She hops off to walk to the boys.] I told you to theathe your immature criticithmth!

[The boys give innocent smiles. Lincoln barely keeps his laughter in before Lisa resumes her seat at the organ.]

Lisa:

…uth all rejoithe amain,
On Chrithtmath day, in the morning

[As the final verse commences, the boys make faces again, each taking turns at pulling at their lips all cock-eyed. Their laughter slowly builds up before rolling out.]

[This time, Lisa catches them with a side glance.]

Lisa:
Litha ith thtarting to get ticked

On Chrithtmath day, on Chrithtmath day

Litha went hunting philithtineth

On chrithtmath day IN THE MORNING!

[Lisa swings about face, pointing what looks like a high-tech carbine rifle. There is a flash of white. As it fades, Lincoln and Clyde are revealed to be in a block of solid ice, their smiles all frozen. Their eyes dart at one another, then at Lisa and back again.]

[Lisa steps off her seat, sighing to herself.]

Lisa: Thome folkth jutht cannot appreciate good tradithional Yuletide dittieth.

[She exits camera left.]
