In this episode, scientists develop a removable tattoo. Sorry, cure for cancer, first things first. Then, Fred Thompson demotes his campaign manager. He'll be replaced by Dennis Farina, but for only one season. Plus, my guest Charles Kaiser has written a history of gay culture. I don't care what books he plugs in the privacy of his own bedroom but don't rub our noses in it. If I've said it once I've said it 287 times -- this is The Colbert Report.
