The 'Zero Days Since Last Blank' meme stems from a classic trope of workplace safety signs, frequently satirized in the animated series Futurama to highlight the incompetence of the Planet Express crew. The visual format typically features a sign where the number is manually changed to zero following a predictable mishap. Online, it has evolved into a versatile tool for mocking repetitive behavior, community drama, or frequent technical glitches. It serves as a humorous way to signal that a streak of good behavior or stability has once again been broken by an inevitable error.
