Explanation
The comic is a multi-panel strip involving a doctor's visit with a wordplay twist. A woman tells a man, "I'm kind of nervous. I have some bad news, babe." He asks, "What?" She says, "You're stegnant." He responds, confused, "Stegnant?" She clarifies: "Pregnant with stegosaurus." A doctor confirms: "Yes, that appears to be a stegosaurus. She is stegnant." In the next panel, the doctor explains that "as a personal choice, if you wish to sterminate your stegnosaurus..." and the stegosaurus, now visible, protests "I'm right here!" The final panel shows a figure (possibly the stegosaurus grown up) glumly noting, "Steven, weren't you done with these by now?" -- referring to the author's penchant for this type of joke.
The humor is a classic Weinersmith portmanteau gag. The entire comic is built on mashing "stegosaurus" into pregnancy-related vocabulary: "stegnant" (pregnant), "sterminate" (terminate), "stegnosaurus" (a further mangling). The joke is essentially a pun taken to its absolute extreme, with the comic fully committing to the absurd premise that being pregnant with a dinosaur is a real medical condition with its own terminology. The final panel is a meta-joke, with what appears to be self-aware acknowledgment that this type of elaborate wordplay construction is a recurring Weinersmith habit. The stegosaurus protesting "I'm right here!" during the discussion of stermination adds a layer of dark comedy by echoing the real-world awkwardness of discussing sensitive medical decisions while the affected party is present.
