in retrospect it’s clear that “heroes in a halfshell” was a riff on “oysters on the half shell,” but it still was a damn strange choice to use wordplay like that in the byline for a franchise marketed at hyperactive preteen children (probably the least likely audience to ever get invited to fancy dinner parties serving oysters on the half shell, and thus the most likely audience to not understand that reference and instead just stare at those words deeply confused because the turtles in the show definitely had both halves of their shells)
