Mark Kleiman (2008): "How clueless is John McCain? He doesn't have a clue. He's never had a clue. He couldn't get a clue if he waited for the clue mating season, found a group of horny female clues, sprayed himself all over with clue pheromones, and did the clue mating dance."
Art Hill (2002): We put people in charge of 'internet strategy' who couldn't get a clue during the clue mating season in a field full of horny clues if they smeared their bodies with clue musk and did the clue mating dance.
Bill Carton (2002): "You couldn't get a clue during the height of the clue mating season on the clue mating grounds if you smeared your body with clue musk (or pheromones, or cluejuice), wore clue bondage gear and did the clue mating dance, surrounded on all sides by thousands of raging, horny clues."
Did this joke exist before 2002?
Edit: (the "periodic" version) George W. Bush could smear himself with clue musk, put on clue bondage gear, do the clue mating dance on the clue mating grounds during clue mating season, surrounded by thousands of raging horny clues, and he still couldn't *get* one!
