Santa Claus is Coming to Town
Here's the reason the song "Santa Claus is Coming to Town" doesn't work.
Christmas is specifically celebrated as part of the Christian religion.
According to Christianity, only God is omnipotent (all knowing).
Therefore JESUS sees you when you're sleeping, knows when you're awake, and knows if you've been bad or good.
This song is clearly sacrilegious and is to be avoided at all cost, lest you put Santa Claus before Him.
