I didn't get that one, either.

I'm curious if you understand this joke (https://i.imgur.com/II5W6Pl.png).

I think it's similar to the Cow Tools panel.

Specifically, the Far Side panel plays on the idea of the fact that cows would have a cow-centric view of the world and would likely develop tools that were alien to us. The other part of the 'joke' is that cows don't build tools (afaik). edit: I think the "3rd" part of the joke is that the tools look like shit, which is what you'd expect from even the most talented cows.

The humor of the space alien joke is similar in that it's pointing out the difficulty that everyone has in understanding how others (other people, other species, etc.) view and describe the world.

Nobody did
