Explanation
The comic shows a single panel featuring three dinosaurs (likely T. rexes). One dinosaur is wearing what appears to be Google Glass-style smart glasses and enthusiastically says, "It's amazing technology. Lets me do everything hands free." Another dinosaur responds with concern: "I hope that doesn't affect the course of evolution."
The joke operates on two levels. First, there is the irony that T. rexes are famously known for their tiny, nearly useless arms, so "hands free" technology would be especially appealing to them -- they can barely use their hands for anything in the first place. Second, the worried dinosaur's comment about evolution is darkly prophetic: if dinosaurs could do everything hands free, there would be even less evolutionary pressure to develop useful arms, potentially making their already comically small limbs even more vestigial.
There is also a meta-joke about Google Glass, which was a much-discussed technology in 2013 when this comic was published. The comic playfully suggests that hands-free technology might lead humans down a similar evolutionary path, making our hands less necessary over millions of years.
The votey panel shows a Venn diagram with two overlapping circles labeled "Topical" and "Irrelevant to the topic," with an arrow pointing to the small overlap region labeled "The best jokes." This is a self-referential comment on the comic itself, which takes a topical subject (Google Glass) and pairs it with something completely irrelevant (dinosaur evolution) to create its humor.
