I feel the need to advertise What the Duck, a web comic about photography. It’s funny and very often, as in the case above, it’s spot-on. Read it!
Speaking about web comics: There is another lesser known one I’m very fond of, namely XKCD (which, according to the author is “[not] actually an acronym”, but “just a word with no phonetic pronunciation”). Here are a few good ones: 1, 2, 3, 4, 5, 6, 7. Make sure you read the mouse-over texts too!
