Thanks to Usual John for sending this head-scratcher; and for introducing us to the work of Guillermo Saldaña. Here’s what Comics Kingdom offers as their “About” for Palurdeando:
Palurdo is an adjective; it means “rustic and ignorant.” Now, we turn this adjective into a verb. What do we get?
Palurdeando is a comic strip where everything has a place. From the simplest joke to the harshest critique. Although it has some recurring characters, such as Bernardino or Holy Pigeon and Little J, everything and everyone is welcome.
So let’s palurdemos for a bit.
Comics I Don't Understand 
The joke may simply be that the gift is inappropriate in that ants ain’t got ears. Their hearing organs are apparently in their knees (they pick up sounds in their legs).
Someone get the lights. We’re done here.
I agree with TedD @2 that Andrew got it @1, but it is worth noting that the tails on the speech bubbles appear to indicate that the ants’ voices are coming from (the ends of) their antennae, rather than from their mandibles.
Given the way ant bodies are segmented, those headphones would fit over their “shoulders” about as well as on their heads anyway…
If the joke is simply that an ant would find headphones to be useless, that seems like something that the first ant would have known.
Who is Aunt Bisle? It’s a Caption I Don’t Understand.
But what’s with the tear or sweat drop?
If it’s a tear, the receiving ant might be touched beyond words. On the other hand, if it were a tear, it should be below the eye (not that ants produce tears).
If it’s a drop of sweat, then what? The receiving ant is worried about what to say? (Not that ants produce sweat.)
I do like the speech bubbles emanating from above the commingling antennae, that was a nice touch.
larK: Good catch; for me, that changes things a bit. The receiving ant is stressed about how to respond, since it can’t really use the gift. Maybe.
I wonder if the headphones are white because it’s a “white elephant” gift. Someone gave the headphones to the first ant, and she’s trying to get rid of them.
As for mandibles/antennae, I thought I read somewhere that ants communicate by rubbing their antenna together when they meet.
The heads on the two ants are strikingly similar. Almost down to the individual hairs. There are a few hairs that are different, but the vast majority of them are identical, including the tufts between the mandibles and markings in the eyes.
I realize artists can be consistent, but that consistency is almost beyond my ability to comprehend. It makes me think there was a cut and paste operation and the “tear” drop or whatever is some sort of artifact.
The “sweat drop” is a common way Japanese anime and manga indicate nervousness.
I agree with Usual John @5: “A(u)nt Bisle” remains a total mystery. Anyone else have an idea? Or would the author perhaps give us a clue?
Odd that the entirety of the receiving ant’s response is an ellipsis (…), which is used to represent omitted (superfluous) words, an intentional silence, or a nervous/awkward silence. Either way, I guess the receiver doesn’t have the heart to tell the giver that their gift is indeed not useful at all. Not sure how that is a joke.
Okay, suppose the ants have a sort of independence or identity movement … “I am not just a number!” as so many have tried to say in our own societies! And then, they might promote an underground practice of taking their assigned numbers and, via a sort of formic reverse-LeetSpeek, turned them into pronounceable names.
Then, with this tiny bit of extrapolation, “31573” could become … “Bisle”!
@ deety (13) – A superb solution, just the sort of obscurity that Mitch is so fond of. It would have worked better in small caps or italics (BISLE), but WordPress does not condone special formatting in post titles.
How would it be pronounced?
Rhymes with “isle”? Rhymes with “fizzle”?
I had supposed on the “fizzle” side of that. Or like “busily”.
Perhaps they’re Anty Noise headphones.
