FAREWELL

Leno's Final ‘Tonight’

Jay Leno hosted his 3,775th and final “Tonight Show” Friday, thanking Bill Clinton, George W. Bush, Monica Lewinsky and Michael Jackson for 17 years of comedic material. He mused about changes that occurred since he started the show, when his hair was “black and the president was white,” and paraded 68 children on stage who had been born by people who met because of the show (“the greatest thing we’ve ever done”). Ratings have been up over 20 percent for Leno’s final week. He also introduced his successor Conan O’Brien, who takes over when Leno moves to NBC’s primetime next fall, and asked viewers to “give Conan as much support as you’ve given me throughout the years.”
