Sam was researching the lore, late one night
When his eyes beheld an eerie sight
For the monster from this lore, began to rise
And suddenly to his surprise

It did the mash, it did the monster mash
The monster mash, it was a graveyard smash
It did the mash, it caught on in a flash
It did the mash, he did the monster mash

From the cramped motel room in the far midwest
To the creepy basement where the vampires rest
The demons all came from their humble abodes
To bust a move with the electrodes

They did the mash, they did the monster mash
The monster mash, it was a graveyard smash
They did the mash, it caught on in a flash
They did the mash, they did the monster mash

Bobby had more than one glass
The party was like a mass!
The guests included Crowley,
Lucifer, and his sass

The scene was rockin', all were digging the sounds
Allistair on chains, backed by some hell hounds
The Winchesters were about to arrive
With their vocal group, 'The Pie-Lovin' Five'

They played the mash, they played the monster mash
The monster mash, it was a graveyard smash
They played the mash, it caught on in a flash
They played the mash, they played the monster mash

Out from the impala, Cas's voice did ring
Seems he was troubled by just one thing
Opened the door, shook his fist and said:

"I dragged you out of hell, I can throw you back in!"

But they still mashed, they did the monster mash
The monster mash, it was graveyard smash
They did the mash, it caught on in a flash
They did the mash, they did the monster mash

Now everything's cool, Cas is a part of the band
Sammy's Monster Mash is the hit of the land
For you, the living, this mash was meant too
When you get to my door, show your fake ID and tell them Dean sent you!

Then you can mash, then you can monster mash
The monster mash, and do the graveyard smash
Then you can mash, you'll catch on in a flash
Then you can mash, then you can monster mash
