We flying the first class
Up in the sky
On a s**t plane
Livin' a lie

The story:

This song came on the radio in art class at school,
and I was singing it out loud (thinking why would
Fergie go on a s**t plane, if she was trying to be glamorous? Was it that she was living a lie and
trying to be glamorous?) I quickly realised when my
friend started singing the real words I was
wrong...and promptly changed them.
