Okay, I have to admit, this is probably the strangest crossover I've ever done. For some reason, even though I haven't heard the song in I don't know how long, it's been stuck in my head for three days. This was my response in an attempt to remove the offending cords, lyrics and bars from my brain, at least temporarily.
The devil went down to Sunnydale, he was looking for a 'Mouth to crack.
He was almost there, books stacked on chair: he was lookin' to cast a spell,
When he came across this young man smirkin' an' a fiddlin' with ax and such.
And the devil jumped upon a library stack and said: "Boy let me tell you what:
"I bet you didn't know it, but I'm a Twinkie eater, too.
"And if you'd care to take a dare, I'll make a bet with you.
"Now you fetch a few doughnuts, boy, but give the devil his due:
"I bet a Twinkie of gold against your soul, 'cos I think I'm better than you."
The boy said: "My name's Xander and it might be a sin,
"But I'll take your bet, you're gonna regret, 'cos I'm friends with the best that's ever been."
Xander, you sharpen up your tongue and aim your ax head well.
'Cos the Devil's loose in the 'Dale and he'll send us all to Hell.
And if you win, you get a nice big snack cake, colored gold.
But if you lose, the devil gets our souls.
The devil unsheathed his blade and he said: "I'll start this show."
And fire flew from his fingertips as he cast right on first go.
And he cackled quick and spoke a spell, and drew a drop of blood.
Then a tingling creeped up Xander's legs as his mouth was filled with crud.
When the devil finished, Xander said: "Well, I see you think you're pretty good.
"But cop a squat, with your Gordian Knot, and here's what's misunderstood."
Pop-culture reference, go boy, go.
The devil's on the mouth of hell you know.
A witty rejoinder, blockin' the door.
"Slayer's gonna be here,"
"That I'm sure."
The devil threw back his head because he thought that he'd just won.
He laid that golden Twinkie on the table, quite blind to what he'd done.
Xander said: "Devil, if you think you'll come on back an' try again,
"I told you once, you son of a bitch, I'm friends with the best that's ever been."
And the Slayer's with a broadsword, hacking up fiends.
The devil's on the run with all his means.
Willow says Thicken, minions can't walk.
Giles with a crossbow,
Oz won't talk.
“Xander,” Willow said slowly as the latest not-so-big-bad fell dramatically to the library floor with a thud and perfectly timedfiddle background music.
“Yeah?” Xander asked after taking a moment to swallow. Even so, white filling was stuck to his cheek and nose.
“Where'd you get that foot long Twinkie?” Willow asked, befuddled by the massive nuke defying snack cake.
Xander just grinned wildly.
“I won it in a bet.”
Needless to say, I don't own "Devil went down tto Georgia" nor do I own Buffy.
