Will Ferrell swung on over to Conan last night to let Conan and Andy try on his woman’s sunglasses (if there is any difference between Conan in those glasses and Tilda Swinton, I’m not seeing it) and to recount his experience receiving the Mark Twain Award from President Obama himself in the Oval Office. And accidentally leaving the Mark Twain Award with President Obama himself in the Oval Office. And getting called back to retrieve the Mark Twain Award by President Obama himself in the Oval Office. More interview below.
