I've been remiss in my capitalistic duties in not pointing out that if you haven't completed your holiday shopping yet, you could do far worse than confound your relatives with a shirt, underwear, mug, or bag from The LOLCODE Store.
If you're unsatisfied with that selection, I stand in awe of the classy selection of Laugh-out-loud cats that Apelad is selling, especially this one. (Absolutely no affiliation, other than admiration.)
