Warning: Contains time waster links

Someone has recently remarked somewhere (this is me not taking notes...) that motivational posters are kind of a Dead Unicorn Trope -- the parodies and deconstructions block out whatever original material might have been there, unless one doubts that there ever was something like a straight, non-ironic motivational poster.

That's because the parodies are funny (which the motivational posters are not). Case in point: 12 Hilarious Motivational Posters from The List Universe.
