Guest(s):Neil deGrasse Tyson
Jon gives the play-by-play of Dick Cheney's mini-Presidency as Bush undergoes a colonoscopy. Senior Presidential Historian Sam Bee puts Cheney's assumption into perspective of other short-term executives. Crisis averted, Stewart turns his attention to a report from U.S. Ambassador to Iran Ryan Crocker, then tries to separate what Bush is and isn't based on the testimony of his "experts." Astrophysicist Neil deGrasse Tyson blows Jon's mind with talk of bacterium and extraterrestrial life.
