The Wall Street Journal staff has rounded up their best and worst ads of 2006. Winners include Apple's "Mac Vs. PC" spots, CareerBuilder.com's Monk-e-Mail web execution and KFC's attempt to foil DVR users by inserting coupons that could only be viewed when watched slowly. Losers include the Head-On spots (can we all agree these are awful and move on?) Wal-Mart/Edelman's attempt to fool us all with a fake blog and DaimlerChrysler's "Dr. Z" series.
