OK, lyrics with the most OTT ludicrous egotistic bravado...

I give you:

Bad To The Bone
George Thorogood & the Destroyers


On the day I was born, the nurses all gathered 'round
And they gazed in wide wonder, at the joy they had found
The head nurse spoke up, and she said leave this one alone
She could tell right away, that I was bad to the bone
Bad to the bone
Bad to the bone
B-B-B-B-Bad to the bone
B-B-B-B-Bad
B-B-B-B-Bad
Bad to the bone

I broke a thousand hearts, before I met you
I'll break a thousand more baby, before I am through
I wanna be yours pretty baby, yours and yours alone
I'm here to tell ya honey, that I'm bad to the bone

Chorus

I make a rich woman beg, I'll make a good woman steal
I'll make an old woman blush, and make a young woman squeal
I wanna be yours pretty baby, yours and yours alone
I'm here to tell ya honey, that I'm bad to the bone

Chorus

'Tell you what/
Give you five and one/
I'll be your lover when I get done'.

Harold Melvin and the Blue Notes - Satisfaction Guaranteed'

i suspect there may be a few hip hop quotes that fit this criteria.

"I'm not sayin I'm number one, uhh I'm sorry, I lied
"I'm number one, two, three, four and five"

That's some chart domination by KRS-One.

I am an antichrist
I am an anarchist
Don't know what I want but
I know how to get it
I wanna destroy the passer by...



And now he presents nature shows about giant bugs.

I wanna destroy the passer by...

allegedly he's still practising before heading out into the street

Every night I tell myself,
"I am the cosmos,
I am the wind"

'I Am The Cosmos' by Chris Bell

They're gonna lay me low (Lay me low)
They're gonna sink me in the snow
They're gonna throw back their heads and crow
When I go
They're gonna jump and shout (Lay me low)
They're gonna wave their arms about
All the stories will come out
When I go
All the stars will glow bright (Lay me low)
And my friends will give up the fight
They'll see my work in a different light
When I go
They'll try telephoning my mother (Lay me low)
But they'll end up getting my brother
Who'll spill the story on some long-gone lover
That I hardly know
Hats off to the man
On top of the world
Come crawl up here, baby
And I'll show you how it works
If you wanna be my friend
And you wanna repent
And you want it all to end
And you wanna know when
Well do it now don't care how
Take your final bow
Make a stand Take my hand
And blow it all to hell
They gonna inform the police chief (Lay me low)
Who'll breathe a sigh of relief
He'll say I was a malanderer, a badlander, and a thief
When I go
They will interview my teachers (Lay me low)
Who'll say I was one of God's sorrier creatures
There'll print informative six-page features
When I go
They'll bang a big old gong (Lay me low)
The motorcade will be ten miles long
The world will join together for a farewell song
When they put me down below
They'll sound a fluegelhorn (Lay me low)
And the sea will rage, and the sky will storm
All man and beast will mourn
When I go
Hats off to the man
On top of the world
Come crawl up here, baby
And we can watch this damn thing turn
If you wanna be my friend
And you wanna repent
And you want it all to end
And you wanna know when
Well do it now Do it now
Take a long last bow
Take my hand Make a stand
And blow it all to hell
Lay me low...
When I go...

Lay Me Low - Nick Cave
