Ogden's Ode to the Boys I Loathe

You're able to quote copyrighted works
without being dragged into court,
but it's hard to legally quote a poem
because a poem is short.

I quote the passage that comes below
not to take away this poet's money.
I quote the poem that follows below,
because it is true, and funny.

My heart leaps up when I behold
A rainbow in the sky;
Contrariwise, my blood runs cold
When little boys go by.
For little boys as little boys,
No special hate I carry,
But now and then they grow to men,
And when they do, they marry.
No matter how they tarry,
Eventually they marry.
And, swine among the pearls,
They marry little girls.

from Song To Be Sung by the Father of Infant Female Children by Ogden Nash

Although I link to the full poem, it – like other poems similarly situated (published before 1978 with copyright notice, renewed with the copyright office, etc.) – is covered by U.S. copyright for 95 years from the point of publication.
