[Immanuel Kant and the Copyright]
[One night as Kant lay somnulative]
[Appeared the categoric imperative]
[Who wrote a maxim in his scrawl]
[On Kant's unblemished bedroom wall.]
[And thereupon Kant set to relate]
[This maxim to the German state.]
[His end achieved, he saw his duties]
[In feasting from the royalties.]
