This Guardian blog post on committing poems to memory brought back (mixed) memories of my eighth-grade assignment (for a social studies class, not an English course, as it happened) to memorize Kipling's "Gunga Din". Rereading that poem now (eighth grade was a long time ago) I wonder how--or if--it is taught today. I can see it causing quite a stir in the more politically correct classrooms of our current times.
What poems have you memorized? Why?
