If you were wondering (which, perhaps, you weren’t) how to create the most memorable ad campaign ever — one that will get stuck in your brain, like the Taco Bell chihuahua; or Coke’s “I’d Like To Teach the World To Sing” song, or even the E*TRADE baby, except for an extra couple of THOUSAND years — there is one marketing marvel that you should study hard: Passover.

You bet your sweet matzo ball! As a holiday, it’s my favorite. As a religious festival, it reminds us of our very foundation as Jews. But as a how-to for would-be Mad Men, it is the Ten Commandments.

But don't sweat it if you find you're not really the Don Draper you thought you could be, because “Passover” is pretty catchy too, and it seems to be working.
