Imagine the next time you join a discussion about . When you start sharing the fascinating facts below, your friends will be absolutely amazed.



Once you begin to move beyond basic background information, you begin to realize that there's more to than you may have first thought.

It's the two-hour series finale of the CW's Life Unexpected (8:00 p.m.), a show with a small but often very devoted fanbase.

PBS's Pioneers Of Television (8:00 p.m. many places, but check local listings) airs its Science Fiction installment tonight. You can watch a preview, in which Leonard Nimoy talks about playing a zombie.

Bob Newhart is guest-starring on tonight's NCIS (8:00 p.m., CBS). Just thought you'd want to know.

Diane Sawyer talks to Mark Kelly, the husband of wounded Rep. Gabrielle Giffords, on tonight's 20/20 (10:00 p.m., ABC).

Another episode of FX's Lights Out — the first critically adored but tepidly rated show FX has put on the air since ... well, since Terriers — airs tonight at 10:00 p.m. But it's on opposite, among other things, BET's The Game, which it rescued from A 2009 cancellation by the CW, to startlingly good ratings last week.

The second episode of Onion Sportsdome, which I reviewed last week, airs tonight on Comedy Central at 10:30 p.m. As I mentioned in that review, I like the second episode more than the first, so if you haven't checked it out — or if you saw the first episode and thought it was so-so — you might give it one more shot at impressing you.

Knowing enough about to make solid, informed choices cuts down on the fear factor. If you apply what you've just learned about , you should have nothing to worry about.
