Charlie Sheen, John Cryer and a bunch of lovable dweebs are sticking around CBS for the foreseeable future.

CBS has renewed its comedic juggernauts 'Two and a Half Men' and 'The Big Bang Theory,' booking them for three seasons and two seasons, respectively.

In other news, VH1 is bringing back 'Behind the Music,' 'The Colbert Report' is heading to the Persian Gulf, and Heather Locklear isn't returning to 'Melrose Place' anytime soon.

(S01E15) "It's my birthday?" - Sam

Even if it wasn't an earth-shattering or intense episode, Samantha Who?'s season finale was satisfying. The episode wrapped up the Chloe/Todd relationship, clarified where Sam and Todd stand, and gave Sam another clean slate (she got the first one after when she woke up from the coma with amnesia). It also marked the first time that all series regulars shared a scene together.

(S01E14) "My mother is having an affair." - Samantha

How fun is it to watch the Newlys interact? I enjoyed this week's episode because it mainly focused on the weird trio that Samantha forms with her parents. Those of you who've been reading my Samantha Who? reviews regularly know how my I love Regina because of her snarky lines and craziness. After "The Affair," Howard is definitely growing on me.

(S01E13) "I can get a guy by tomorrow." - Samantha

This line may not have been the funniest one of the episode but it had major implications for both Sam and Todd. What if she hadn't been able to find a date for the gallery show? What if she found a guy who turned out to be prince charming and not a mugger? Those two possibilities could have totally changed the ending of the episode, meaning that Todd could still be thinking of Chloe instead of Sam. Luckily for us, Sam found Jerry O'Connell, who was trying to get in his car using a hanger since his Carpoolers friends left him on the curb, and he turned out to not be the guy for our Sam.

(S01E12) "Your friend. I want her. Make it happen." - Chapman

If ABC hadn't decided to air 15 episodes of Samantha Who? this season, this episode could have served as a season finale. It not only sent Sam in the unknown (she quit her job at the end of the episode) but the episode also ended with an important kiss that could have Todd rethink his decision to give Chloe a chance and have us wonder for months what his decision would be. But, thanks to SW? being popular, we will get answers to these questions before the season ends and will get a new set of questions to ponder on all summer long.

(S01E11) "Marry me." - Winston Funk to Sam

This week's episode of Samantha Who? ended up being quite satisfying and I'm not just saying that because the stable boy kissed the amnesiac heroine (which surely pleased the 52.5% of people who voted for "Sam & Todd forever" in our last poll). We were treated with crazy Regina, romance novelist wannabe Dena, teenager with a huge crush Andrea, and smitten with a potential son-in-law Howard. What more can we ask for? Especially after that "look at what you made me do" kiss!

(S01E10) "I love you." - Todd to Chloe

First, I must thank ABC for the fun Samantha Who? marketing campaign they did these past two weeks or so. I know that the fun ads during which Samantha and her mother talked about a song that meant a lot to Regina, or during which Samantha presented her boyfriend, er, ex-boyfriend, Todd, had an effect on some non-watchers (a few of my friends asked me what the show was about and planned on watching the show this week). Let's hope more join the fun.

Secondly, our favorite amnesiac is back on TV! Yay! This cutesy series is definitely one I enjoy watching a lot thanks to Samantha's duality (evil-Sam versus good-Sam), very well played by Christina Applegate, and thanks to Jean Smart and the devilish Andrea, played by Jennifer Esposito.

That said, let's get to the important part of this post: the review.

(S01E09) "Without you, I would be nothing." - Sam to Regina
"You wouldn't be nothing; you'd just be less." - Regina

This week's episode was important in Samantha's life: she slept with a man (thus ending her "virgin" status), she learned to express her feelings and said "I love you," she suffered her first post-accident break up and she learned to be a better boss.

(S01E08) "Having amnesia is like an obstacle course." - Samantha

I never suffered from amnesia but from what we've been seeing for now eight episodes, amnesia does seem to be like an obstacle course or, as the cast picture on the right shows, a maze. Samantha has to overcome obstacles put in her path because she doesn't fully know herself or the world she lives in. She must make her way through life without having a map to guide her. It's trial and error. This week, Samantha had to decide between lying and telling the truth and how it would affect her father.

(S01E07) "Everyday with me is an adventure." - Samantha

That's how I feel when I watch Samantha Who?, one of my guilty TV pleasures. We never know what to expect every week because the lead character doesn't know herself. The series has been one of the most popular new comedies of the season partially because of its lead-in (Dancing with the Stars) and its star (lovable Christina Applegate). I'm not ashamed to say that I enjoy it for its bubbly storylines (we all need a few series in our weekly watch list that don't require us to think too much), its lead character/actress, the devil/angel parts played by Andrea and Dena, and for Jean Smart!

TV Guide reports that Christina Applegate's new ABC series is now titled Samantha Who? As Bob reported about a week ago, the network failed to get permission from the estate of Dr. Seuss to use the title Sam I Am, which was the original title of the series but also refers to the Seuss book Green Eggs & Ham.

Before settling for Samantha Who?, the network and the people behind the show briefly retitled this series Samantha Be Good.

Jennifer Esposito is the newest member of Engine 62, according to TV Guide. Ausiello is reporting that Esposito's character will join the cast right away during the season four premiere. She'll play a volunteer firefighter who has a history with Tommy Gavin (Denis Leary). And, her character is supposedly also going to become a love interest for Tommy as the season progresses.

Well, lucky Denis. Jennifer Esposito is gorgeous! She was spectacular in Crash, but the first thing that comes to mind when I hear Jennifer Esposito's name is her guest stint on one episode of SVU way back in 2000. She played 'Sara Logan', a sarcastic television reporter who goes public with her own rape. She has a sort-of father/daughter relationship with Det. Munch (Richard Belzer) that ends up being very heart-wrenching.

The absolutely stunning (seriously, she's beautiful!) Jennifer Esposito has signed on for a leading role in a FOX comedy pilot. She'll replace actress Alicia Witt, who dropped out of the project last week due to "creative differences". The comedy is called More, Patience and it's about a New York (where else?) psychiatrist who can't handle her own life. Ah, the irony.

Esposito is also on the WB's Related, which is currently fighting for a time slot on the new The CW network. Does that mean she'll be doing both shows? Busy lady.
