Achilles' Bum

How will I find my final freedom
When earthly troubles yank me back
Anchoring me to this paltry kingdom
Where warring children tic and tac
I tried to escape in a soaring rocket
And aeroplanes launched me through heaven
But I had no license to unlock it
I merely played like I was seven
The boundaries of this biped life
Equal those empowered by every wife
And husband who keep their child in check
From accidentally breaking their neck
Mother, hear how your land-slave sings
Reward me now with a pair of wings!
