I've never understood the meaning of the term "Pearls before Swine" and never bothered to look it up (laziness mostly). I've chalked it up as an unfunny comics strip that is obscure.
But today I read a blog post by Linus (yes, the creator of Linux) about his experiences at a Night before Oscar Party. It is hilarious, you should go read it, NOW. The title of the blog was "Pearls before Swine". This time I decided to look up the meaning of that term and I don't regret doing so. I think it'll come in quite handy in the future. :)
Pearls before Swine (from Wikipedia):
things (such as pearls) should not be put in front of people (or in this case, swine) who do not appreciate their value
