Jay Leno went out (again) on a high note.

The host's final Tonight Show Thursday drew 14.6 million viewers and a 3.8 in the adults 18-to-49 demographic, making it the show's biggest audience since Jerry Seinfeld visited the night of the sitcom's finale on May 14, 1998. Leno's first exit in May 2009 drew 11.9 million.
