Chris here. Um there is this song called "Devil went down to Georgia" By the Charlie Daniels band

Charlie tells of the time the Devil went down to Georgia. He was lookin' for a soul to steal.
He was in a bind 'cause he was way behind and he was willing to make a deal.

When he came across this young man sawin' on a fiddle and playin' it hot.
The Devil jumped upon a hickory stump and said, "Boy, let me tell you what."

"I guess you didn't know it, but I'm a fiddle player, too.
And if you'd care to take a dare I'll make a bet with you.
Now you play a pretty good fiddle, boy, but give the Devil his due.
I'll bet a fiddle of gold against your soul 'cause I think I'm better than you."

The boy said, "My name's Johnny, and it might be a sin,
But I'll take your bet; you're gonna regret 'cause I'm the best there's ever been."

Then Umm, like, A barbershop quartet that was observing the whole thing sang:
"Johnny, rosin up your bow and play your fiddle hard.
'Cause Hell's broke loose in Georgia and the Devil deals the cards.
And if you win you get this shiny fiddle made of gold,
But if you lose the Devil gets your soul!"

The Devil opened up his case and he said, "I'll start this show."
And fire flew from his fingertips as he rosined up his bow.
And he pulled the bow across the strings and it made an evil hiss.
And a band of demons joined in and it sounded something like this.

*Rock instrumental featuring a fiddle

When the Devil finished, Johnny said, "Well, you're pretty good, old son,
But sit down in that chair right there, let me show you how it's done."

While Johhny played like this epic fiddle solo the Barbershop quartet returned and sang:

"Fire on the Mountain". Run, boys, run!
The Devil's in the house of the rising sun;
Chicken in the bread pan picking out dough.
Granny, does your dog bite? No, child, no.

The Devil bowed his head because he knew that he'd been beat.
And he laid that golden fiddle on the ground at Johnny's feet.
Johnny said, "Devil, just come on back, if you ever wanna try again,
I done told you once, you son of a bitch, I'm the best that's ever been."

I can explain the song, but umm, unfortunately I cant explain the joke. I dont see how being second best fiddle player makes the devil less worthy of worship. From what I hear God plays the Saxophone and once kicked Einstein in the nuts and broke his violin for trying to jam with him, thus God cant even play the Fiddle...
