Alf, the Poet, sings:

You better be short,
You better be fat,
You better be alt,
I'm tellin' you that!
Buddha Claus is comin' to town.

He's chantin' "Namu,"
Or is it just "Nam?"
He'll tell you it's "Mu"
As fast as he can.
Buddha Claus is comin' to town.

He's sitting when you're sleeping,
He sits when you're awake,
He sits when you've been bad or good,
So you know your ego's fake.

So...

You better be short,
You better be fat,
You better be alt,
I'm tellin' you that!
Buddha Claus is comin' to town.
