Here's a parody involving Robin Hood and Santa

Chorus:

Robin got run over by a reindeer
Walking back from Sherwood Christmas Eve
You can say there's no such thing as Santa
But as for me and Friar Tuck, we believe

All the outlaws down in Sherwood
Have switched their green wool tights to black.
Little John is on a bender,
Trying to find Santa and his pack.

We found Robin Christmas morning,
Lying face down in the snow.
He had hoofprints on his forehead
What an awful way for Robin Hood to go.

Lady Marian is crying,
And Will Scarlet's quite distressed
It's not Christmas without Robin
Nottingham's not really at its best.

Friar Tuck will do the requiem
"Dies Irae" will be sung
The gallant men who marched with Robin
Now will march with their bowstrings unstrung
