Here's something you don't see all that often. It's comedian Albert Brooks on a talk show in 2011! Then again, Brooks recently did join Twitter, too, to promote his new book. So perhaps it's not as much of a surprise. Still enjoyable, though.

Even if he sold most of his material. Roll the clips for a proper explanation.

 

Part two includes Brooks responding to Osama bin Laden, Donald Trump and other villains. Oh, and Brooks and Letterman kiss on the lips, despite Letterman having a cold. Talk about going viral!

 

As for that new book of his, you can check out 2030 via Amazon.com:
