Must be seen to be believed

The U.S. Copyright Code, in verse. A for effort, B for rhyme. Best stanzas:

302

A copyright lasts seventy years
After you're dead
Or ninety years generally
If they can't find your head

303

If written before '78
But published only since
Go back to the last section
And try not to wince

My comment:
I love you, internet.
