I’m fond of a number of Bob Rivers’ Twisted Christmas songs:
Chipmunks Roasting on an Open Fire
Walkin Round in Women’s Underwear
Wreck the Malls
GRANDMA GOT DISMEMBERED BY A CHAINSAW
Dr Demento has played some truly demented songs, like:
I found the brains of Santa Claus underneath my bed
They were in a pickle jar, I wonder if he’s dead
Oh they smell like dried up tuna and look more green than red
I found the brains of Santa Claus, I wonder if he’s dead
