good-evening
Explanation
The Joke
A woman in lingerie stands in a bedroom doorway and announces to her partner: "Good evening. I have covered the safest portions of my endowment with thousands, upon thousands, of individual eggs." Her partner, lying in bed, thinks: "Now God, yeah, that was hot. We might have our groove back." But then he wonders: "Do we not have daring waivers?" In the final panels, two ghostly figures discuss the situation: one says "The patriarchy will fail" and the other responds "Tell him it's pretty free," suggesting a bizarre supernatural commentary on the proceedings.
The comic takes the concept of a romantic "surprise" in the bedroom and replaces the expected seduction with something absurd and unsettling -- covering oneself in thousands of eggs. The partner's confused but tentatively positive reaction ("we might have our groove back") satirizes how people in long-term relationships sometimes go along with increasingly bizarre attempts to "spice things up" rather than admit they're confused or disturbed.
The Humor
The comedy derives from the extreme disconnect between the romantic setup (lingerie, bedroom, "good evening") and the deeply strange content of what's actually being proposed. The woman's formal, almost clinical language ("the safest portions of my endowment") contrasts absurdly with the intimate setting. The partner's internal monologue -- trying to convince himself this is sexy -- captures the relatable experience of wanting to be supportive of a partner's efforts while being thoroughly bewildered. The ghostly figures at the end add a surreal layer that prevents the joke from being merely about bedroom awkwardness, pushing it into SMBC's characteristic territory of existential absurdity. The title text ("I'm sure this is already a thing, but I would appreciate not getting an email about it") is a classic Weinersmith meta-joke, preemptively asking readers not to inform him if egg-based intimacy already exists in reality.
