"A Christmas card from Santa" joke

I'm sending this card to tell you
That taxes have taken away
The things that I really needed -
My workshop, my reindeer, my sleigh,
Now I'm making my rounds on a jackass,
He's old, he's crippled, he's slow,
So you'll know if I don't see you at Xmas,
It's 'cause I'm out on my ass in the snow.
