Hmmmm, reciting a whole poem from memory.

That's a tricky one.

After extensive self-interrogation, I am pretty sure that I cannot recite an entire poem either, unless you count The Horseshoe Nail (more a morality tale, or lecture on historical contingency than a poem, I'd say), or the 23rd Psalm...and I suspect that there are bits of both I'd leave out.

Shocking, really.
