Castiel the Human Angel (Rudolph the Red-Nosed Reindeer)

You know Michael and Luci

Gadreel and Ezekiel

Gail and Metatron

Ingrid and Balthazar

But do you recall

The most famous angel of all?

Castiel the human angel

Helped two quite unlucky bros

And if you ever saw them

They would even say it blows

All of the other angels

Used to love and call him God

They never let poor Cas

Live an easy angel life

Then the evil scribe of God

Known as Metatron

Stole the grace that burned so bright

Right out from the angel's chest

Now Cas is only human

And he shouted in despair

Castiel the human angel

You'll get your grace back, I swear
