The best commercials this week don't have too much in common, except that they're all worth a watch. The U.S. government tries to dissuade teens from texting while driving with a disturbing PSA; a Thai insurance company shows the karmic power of a good deeds; a British supermarket chain goes back to basics with a spot about personal ownership; Canon looks behind the lens; and Alison Brie and Adam Scott host a non-VIP party for Smirnoff.
