I have been looking for a reason to post this clip of Russel Brand who is a UK comedian, writer and actor and now I have it. Brand's book My Booky Wook was a surprising hit for Hachette and he has now jumped to Harpercollins which will release the title in the US. In the UK, his title sold 600K units and topped charts for weeks. The deal also covers an expected sequel. Brand was in the movie Forgetting Sarah Marshal. released earlier this year.
Here is some video from Letterman.
