basic puns and rhyming are niche forms of art?

Puns and rhyming can generally be translated across languages. I don't think its controversial to say that its possible to get most of what a piece of art is trying to say through a translation.

If anything comedy is an excellent way of learning a language: the use of double and triple entendres helps to quickly get exposed to alternate meanings and misunderstandings of words. Comedy aimed at learners or multilinguals can also help, plenty of anglos who learned Spanish can relate to "feeling pregnant" early on :)
