If you have an urge for exploration into relevance while still looking at drawings of dinosaurs, follow the link on the reader art section of the Dinosaur Comics page to "Dadasaurus Rex" which takes advantage of the fact that Dinosaur Comics artwork is static and only the dialogue changes. A new comic is generated each minute from randomly-selected panels.
@Nathan: I assumed it was supposed to be additional evidence that he was charming. But I suppose I don't know how many girlfriends a dinosaur is likely to have had. So maybe I was taken in, and there was no actual relevance.
I would infer from T-Rex's statement that he believes that five is a sufficient volume of girlfriends to prove that he's charming, whether or not that's objectively true.
On the other topic, Dinosaur Comics does in fact visit linguistic topics with some frequency. At least, with far greater frequency than many other web-comics. But whether discussing linguistics or other topics, I always find it an enjoyable read.
