What a buzz kill. This long-running spot from director Joe Pytka was the toughest of all tough-love PSAs. "This is your brain," the announcer snapped at an intact egg. Then, at a sizzling one, "This is your brain on drugs." That stark food for thought may have saved a few million neurons and certainly provided rent money for many a comedy writer: "This is your brain on drugs, with a side of bacon," SNL mocked in one satire. Any questions?
