As a foreigner who learned English, one of my most memorable lessons was when we were given "the Jabberwock" as an exaple of old English to explain it even if we didn't understand some words (on the most advanced English level in the school). After we tried to make sense of it from the grammar, context, word root, etc and gave an explanation of each part and compared notes it was revealed that it was a made up language. Still, it's incredible how much there was to understand.
