For better or worse, Jay Leno will retake his Tonight Show desk Monday evening, after months of controversy thanks to NBC’s booting of Conan O’Brien after a mere seven months.

Leno hopes to regain his dominance in the ratings; rival David Letterman has greatly benefited from NBC’s late-night scrambling.
