biology-3
Explanation
This comic satirizes the sci-fi trope of aliens wanting to have sex with humans by pointing out the absurd biological implausibility -- and then undercutting the critique by pointing to a beloved real-world example.
Two characters are stargazing. One argues that movies where aliens want to have sex with humans are "totally implausible," noting that aliens would be biologically incompatible with humans, not even from the same tree of life. He then proposes a thought experiment: imagine the reverse scenario, where humans show up at an alien planet and want to have sex with everyone there. He argues you might call this immoral or goofy, but asks whether any part of you would consider it "implausible" -- suggesting that, actually, humans are exactly the kind of species that would try to mate with aliens.
The punchline comes when the listener goes silent, and the first character asks, "Baffled by my logical reasoning?" The response: "No, realizing you just described the original Star Trek." This is a direct reference to Captain Kirk's notorious reputation for romancing alien women across the galaxy in the original Star Trek series (1966-1969), where virtually every episode featured Kirk seducing or being seduced by a humanoid alien.
The humor operates on two levels. First, there is the self-deprecating observation about human nature: the reason alien-sex movies are not implausible is not that aliens would want us, but that we would absolutely try. Second, there is the pop-culture recognition that this exact scenario already exists as one of the most iconic science fiction franchises ever made, and nobody blinked at the premise for decades. The comic turns a philosophical argument about biological plausibility into a commentary on how Star Trek normalized interspecies romance without anyone stopping to question it.
