Ears
[Cueball is sitting with his back towards Megan who is lying on her back on a grassy hill. Both are looking up at a sky with small puffy clouds (one large, two small, and four tiny). In the background fields are visible below their vantage point.]
[Same setting, but with the clouds removed, to make room for Cueball's text.] Cueball: Do you ever just look up at the sky and wonder...
[Same setting, zoomed a bit out to make more of the background fields visible, still with the clouds missing due to the text from the two people.] Cueball: "What are normal peoples' ears shaped like, that earbuds stay in without falling out?" Megan: Man, who knows what's going on in there.

Cueball and Megan are sitting in a park together and appear to be cloudwatching. Cueball asks if Megan has ever looked up in the sky and wondered, suggesting that he is thinking deep thoughts while allowing his mind to wander, what "normal" people's ears are shaped like; that their earbuds stay fitted inside their ears instead of falling off. It is possible, but not evident, that Cueball is listening to some audio device through earbuds , and his wondering is caused because he looked up at the sky and they fell out, leading to his thoughts about what it would be like to have "normal shaped ears" that would allow him to wear earbuds without this happening. (This joke is directed towards a large group of people who cannot use earbuds successfully because they fall out.) Megan's response could either be making fun of Cueball (whatever goes on in his head with the random conversation points he tends to bring up) or agreeing with him that earbud wearers' ears are mysterious.
The comic appears to be a variation on a famous and often-quoted fragment from Voltaire 's satirical novella Candide , wherein Dr. Pangloss states that we live in ' the best of all possible worlds ', among other reasons because '…noses were made to wear spectacles, and so we have spectacles'.
The title text is a play on conspiracy theories wherein the human race is being assimilated by aliens, and the person coming up with the conspiracy theory thinks he is one of the few "free" survivors. The use of "brain slugs" in particular may be a reference to the Animorphs book series, a nostalgic favorite of Randall's, in which humanity is being colonized by parasitic alien slugs called Yeerks , that enter a human's brain through the ears and can control them. Randall/Cueball here is suggesting that the reason most humans can wear earbuds is because the Yeerks hold the earbuds in place.
Another possibility, given the earbud/music reference, is that Randall is making a joke about earworms .
