First Lady Michelle Obama stopped by The Tonight Show Starring Jimmy Fallon  this week, but she didn't just settle for making an ordinary appearance. (Has she ever? ) She turned up as a special guest on Fallon's series "Ew!" At first, it was just him and Will Ferrell , which is cool enough, but then the First Lady popped in to discuss the Olympics, healthy eating, and omega-3 fatty acids — or should I say, "ah mah-ga thray faddy ah-sads." There's so much good stuff here, including Ferrell making out with a picture of himself, and, of course, a visit from Sara's (Fallon) stepdad, Gary.
