All my bags are packed, I'm ready to go
I'm standin' here outside my Chinese apartment door
I just gotta hail a taxi, and then I'll say goodbye
The dawn is breakin', it's early morn
The taxi's comin', and he's blowin' his horn
Already I'm so happy I could jump for joy
Your kids hated English and disrespected me
When I told 'em to do their work,
they told me they'd do no such thing
So now I'm showing you who's really the boss of me
'Cause I'm leaving on a jet plane
I know I'll never, ever, EVER be back again
Oh, man, it's so great to go
There's so many times your kids let me down
So many times they just played around
To them an English teacher doesn't mean a thing
Every place I go, it quickly gets old
Every thing I buy flattens my billfold
When I come back I'll be 101
Your kids hated English and disrespected me
When I told 'em to do their work,
they told me they'd do no such thing
So now I'm showing you who's really the boss of me
'Cause I'm leaving on a jet plane
I know I'll never, ever, EVER be back again
Oh, man, it's so great to go
Soon I'll be leavin' Chinese airspace
There's a big ol' smile across my face
I can now close my eyes and head for Gimhae airport
Dream about the days and all my likes
Now that I don't have to teach your bratty tykes
I wouldn't wish your kids on my very worst enemy...
Your kids hated English and disrespected me
When I told 'em to work,
they told me they'd do no such thing
So now I'm showing you who's really the boss of me
'Cause I'm leaving on a jet plane
I know I'll never, ever, EVER be back again
Oh, man, it's so great to go
And I'm leaving on a jet plane
I know I'll never, ever, EVER be back again
Oh, man, it's so great to go
Now I'm leaving on a jet plane
(Ah ah ah ah)
Leaving on a jet plane
(Ah ah ah ah)
Leaving on a jet plane
(Ah ah ah ah)
Leaving on a jet plane
(Ah ah ah ah)
