The gastropod divorce papers have been finalized! In this brilliant biological pun, we see the key morphological difference between snails and slugs—one literally got the shell in the settlement. While taxonomically distinct (slugs aren't just "homeless snails"), the joke cleverly plays on the visual similarity between these mollusks. The shell as "the house" in divorce terms is pure evolutionary comedy gold. Next time you spot a slug sliming along, just remember it's not bitter about the breakup, it's just embracing its naked lifestyle choice!
