You better watch out
You better not cry

You better not pout
I'm telling you why
(You know that)

Santa claus is comin' to town
Santa claus is comin' to town
Santa claus is comin' to town

Usher:
He's checking it twice
Mandy:
He's gonna find out
Who's naughty or nice
(You know that)
Both:
Santa claus is comin' to town
Santa claus is comin' to town
Santa claus is comin' to town
Mandy:
He sees you when you're sleeping
He knows when you're awake
Usher:
He knows if you've been bad or good
So be good for goodness sake
Usher:
So you better watch out
You better not cry
Mandy:
You better not pout
I'm telling you why
(You know that)
Both:
Santa claus is comin' to town
Santa claus is comin' to town
Santa claus is comin' to town (x3)
