I get only 43% of the cartoons posted on XKCD. For example, I didn’t get this recent one on Google+ and had to go all the way to Explain XKCD. Even that didn’t help much. But I do get the easier ones and swear by XKCD in any andho-mein-kaana-raja type situation. And then there are times when I TOTALLY get an XKCD comic. Like TOTALLY. This comic was a part of those rarest-of-rare moments.
