First up, a rewritting of "Welcome To The Jungle" by Guns N'Roses.
Welcome to the Hellmouth
It's all fun 'n' games
Things that go bump in the night
are sure glad you came
The Master's about to rise, so you better take heed
You better get outta here
Cause it's time to feed
In the Hellmouth
Welcome to the Hellmouth
Watch it bring you to your shun n,n,n,n,,n,n,,n,n,n,,n,n,,n knees, knees
They wanna watch you bleed
Welcome to the Hellmouth
I gotta go and slay
Hunt them all down in the night
Get to class in the day
I'm not just a teenage girl
There's more than what you see
Buffy the Vampire Slayer
Vamps better not mess with me
In the Hellmouth
Welcome to the Hellmouth
You'll see what I mean
When I'm dusting up the scene
Welcome to the Hellmouth
It gets weirder everyday
My boyfriend is a vampire
My best friend just turned gay
My human boyfriend left
I'll be with Spike eventually
But if an apocalypse needs stopping
Better put in a call to me
In the Hellmouth
Welcome to the Hellmouth
Watch it bring you to your shun n,n,n,n,,n,n,,n,n,n,,n,n,,n knees, knees
They wanna watch you bleed
And when you die you never
Ever gonna stay dead, so dead, so dead, so dead YEAH!
You know where you are
You're in the Hellmouth baby
You're gonna die
In the Hellmouth
Welcome to the Hellmouth
Watch it bring you to your shu n,n,n,,n,n,,n,n,n,,n,n,,n,n,,n knees, knees
In the Hellmouth
Welcome to the Hellmouth
You'll see, you'll see what I mean
In the Hellmouth
Welcome to the Hellmouth
Watch it bring you to your shun n,n,n,n,,n,n,,n,n,,n,n,,n.n, knees, knees
In the Hellmouth

Watch it bring you to your
