===Interlude===
I find this a bore, let's double it up.
Oh, bring it on, sister! We will mess your shit up!
[Bert and Santa Claus enter the battle]
Bert. Santa. Mary. ...Mrs.?
[Mrs. Claus hisses]
===Verse 1===
Extemporized before your very eyes,
Love to laugh at jolly guys I despise!
I likes what I raps and I raps what I likes,
Cause damn right Van Dyke rocks these mics!
You’re an icon of greed that’s perverted the season,
You give coal to bad kids, Mary teaches ‘em reason,
She's super classy, swagolistic, extremely ferocious!
Super classy, swagolistic, extremely ferocious!
I could do this whole verse backwards, but I truly feel
I’m through wasting my time, because you’re not even real!
===Verse 2===
Please don’t act like you’re some kind of saint, Nick.
Always spying on minors: That’s jailbait, prick!
==Trivia==
