· Who is responsible for the Obama as Joker posters showing up around L.A., Matt Drudge wants to know! Here's a theory: Some bored "guerrilla artist" who wants to be noticed?

· Local dialect coaches rejoice! Flavor-of-the-Month Sam Worthington is filling the role vacated by Tom Cruise in The Tourist, playing the part of an American abroad used by an Interpol agent (Charlize Theron) to track down a criminal.

· The Internet is ablaze with news that Sesame Street will be parodying Mad Men this season, with a producer hinting only to "think about the title 'Mad Men' and think about the emotional curriculum that might be linked to that." The best we can make out is that the show will introduce children to the smooth, tasty joys of filterless smoking.
