Here's what's happening today in pop culture:

• President Barack Obama appears on "Late Night With Jimmy Fallon" and the right-wing noise machine (d/b/a Fox News) has a collective (and suspiciously rehearsed) snit about it. This causes the great Charlie Pierce to issue a much-needed reality check, complete with Richard Nixon's "Laugh-In" appearance. (I swear, if Obama walked on water, Gretchen Carlson would whine that he can't swim.) [Esquire]

• Two iconic Manhattan residences -- a brownstone that was the exterior location for Holly Golightly's apartment in "Breakfast at Tiffany's," and the townhouse identifiable as the home of Carrie Bradshaw in "Sex and the City" -- have sold for millions each. [The Hollywood Reporter]

• Martin Scorsese is a convert to 3-D, and vows that all his movies from now on will be shot that way. [AP]
