This is a parody of "Pretty Fly for a White Guy" by The Offspring.
 
Gourry's explaining to Lina that he's not giving up the Sword Of Light...
[The quotes are Lina singing]
 
"Give it to me, Gourry!"....No way! It's mine!
"Give it to me, Gourry!"....No way! It's mine!
"Give it to me, Gourry!"....No way! It's mine!
"And I'm not gonna rest until the Sword of Light is mine, guy!"
 
(music)
 
"Gourry, give it to me by the time I count to three..."
 
This girl has had her fair share
Of weapons in the past,
But she is so destructive --
They're broken way to fast!
And now she wants my light blade,
But still she doesn't see...that
She's never gonna get it
'Cause this sword belongs to me!
 
"Come on Gou-r-ry,
Please give the sword to me!
It'll amplify my power then no one will mess with me!
So you'll just hear me whine 
Until you say it's mine!"
For you, NO WAY!!!
It's yours? NO WAY!!!
"Come on Gourry, dear
Why don't you give it here?"
Because this thing's been in my family for a couple thousand years!!!
"Just gimme the Sword of Light, and..."
HEY!!! HEY!!! Get your hands off that thing!
 
"Give it to me, Gourry!"....No way! It's mine!
"Give it to me, Gourry!"....No way! It's mine!
"Give it to me, Gourry!"....No way! It's mine!
"And I'm not gonna rest until the Sword of Light is mine, guy!"
 
She needs to get some food
Not just any will suffice...
She wants to stuff her face
She don't care about the price
She orders several helpings and
She swallows every bit...
Then starts about the sword again
THIS GIRL JUST DOESN'T QUIT!!!
 
"Just give it up Gourry,
That sword belongs to me!
But I'll let you hold on to it since you're protecting me!"
You're headband's way too tight --
This ain't your Sword of Light
The sword is mine!
The sword is MINE!
I'll say it one more time!!
THE SWORD OF LIGHT IS MINE!!!
It'll stay within MY family till the end of space and time!!!
"I'll take my sword of light, and..."
HEY!!! HEY!!! Get your hands off that thing!
 
She's losing her temper, yeah
Her eyes are blood red...
And smoke is pouring out of her
Inflated little head
Friends say she's tryin' to hard
And it's gonna get worse...
'Cause in her own mind, she thinks that
The sword is hers!
 
"Give it to me, Gourry!"....No way! It's mine!
"Give it to me, Gourry!"....No way! It's mine!
"Give it to me, Gourry!"....No way! It's mine!
"And I'm not gonna rest until the Sword of Light is mine, guy!"
