Song of the Insufficiency of Human Endeavor

[PEACHUM]
A man lives off his head
His head won't see him through
Inspect your own. What lives off that?
At most a louse or two
For this bleak existence
Man is never sharp enough
Hence his weak resistance
To its tricks and bluff

Aye, make yourself a plan
They need you at the top!
Then make yourself a second plan
Then let the whole thing drop
For this bleak existence
Man is never bad enough
Though his sheer persistence
Can be lovely stuff

Aye, race for happiness
But don't you race too fast
When all chase after happiness
Happiness comes in last
For this bleak existence
Man is never pitiful enough
All his loud insistence
Is a load of guff

Man could be good instead
So slug him on the head
If you can slug him good and hard
He may stay good and dead
For this bleak existence
Man's not good enough just yet
Do it without assistance
Slug him on the head
