Survival of the horniest

This place is way too overcrowded
Sometimes I wish that I could leave
Why can't we find another planet?
And leave the fools here to breed

The human race is being won
By the ones with the biggest guns
Nothing in their minds and nothing to offer
Except of course, mass reproduction

Condoms, pills, abortions
Why can't they just choose one?
We've got to stop this accumulation
Of unwanted kids to crack-whore moms

What ever happened to survival only of the fittest?
Why do we drag along the weak?
They're slowing down our evolution
And our future's looking bleak

What happened to survival only of the fittest?
Why do we let them multiply?
They're slowing down our evolution
Mother nature would let them die
