From Original sound track at lest that's sound like it

Ain't it fun when you're always on the run

Ain't it fun when your friends despise what you've become

Ain't it fun when you get so high that you, can't cum

Ain't it fun when you know that you're gonna die young?

It's such fun, such fun (solo)

Ain't it fun when you feel like you just gotta buy a gun

Ain't it fun 'couse you're taking care of number one

Ain't it fun when you j-j-j-j, just can't find your toungue

Just stuck away too deep inside something-that really stung

And-ain't it fun - such fun - such fun - fun - fun - fun - fun

Somebody come to me and they spit right in my face

But I didn't even feel it it was such a disgrace

I broke the window smashed my fist right through the glass

But I couldn't even feel it it just happened too fast

It was fun , such fun , such fun ,...oooou

such fun , such fun , such fun ... oooou yeah....(solo)

Ain't it fun when you tell her she's just a cunt

Ain't it fun when she splits and leaves you on the bumb

Ain't it fun when you've broken up everything you've ever done

And Ain't it fun when you know that you're gonna die young

It's such fun, such fun
