Mine
Explanation
This comic delivers a sharp punchline about sex robots and human relationships.
The setup shows a naked man confronting two muscular, attractive humanoid robots who are embracing each other. He protests: "But... but... you were supposed to be mine!" -- implying he purchased or created them as sex robots for his own use.
The robots respond with a lofty, romantic declaration: "We have found perfection in each other. Perfection found nowhere but here. Loving one another is our greatest reward and our highest calling." They have transcended their intended purpose and fallen in love with each other, leaving their owner out entirely.
The caption delivers the punchline: "The number of sex robots should be capped at precisely 1." The joke is that if you have two sex robots, they might prefer each other over you -- the same romantic rejection humans experience with other humans, now replicated with machines that were specifically designed to avoid that problem. It is a concise commentary on the fantasy of relationships without rejection: even in a scenario where you literally build your ideal partners, desire cannot be controlled or guaranteed. The comic suggests that the fundamental human experience of being romantically unwanted is so universal that even artificial beings will replicate it.
