On the one hand, we'll never experience childbirth. On the other hand, we can open all our own jars.

Framed as a wry “pros and cons” of being male, the line juxtaposes an unbridgeable biological difference—men not experiencing childbirth—with a trivial, stereotypically masculine “advantage”: physical strength applied to opening jars. The humor comes from the disproportion between the magnitude of childbirth and the banality of the compensation, implicitly acknowledging that no everyday perk meaningfully balances that experience. Read more broadly, it satirizes gendered comparisons that try to “even the score” with small conveniences, and it pokes fun at cultural expectations that men should be strong, handy, and unfazed, even when the comparison is absurd.
