3.
Favorite New Romance
Sheldon and Leonard aren't thrilled, but Penny really loves the idea of a romance between Leonard's dad and Sheldon's mom. I mean, come on, how could we not be excited about that?
4.
Most Underutilized Character
For some reason, Leonard's story arcs haven't felt very significant lately, other than his marriage with Penny. If there's anything we'd like to see next season, it's something of more substance for Leonard.

Best Valentine's Day Celebration
The best way to celebrate Valentine's Day? To crash your friends' live Fun with Flags episode wearing cupid outfits and throwing confetti at the camera. Leonard will apparently wear anything. Hey, he's a good sport.

7.
BrOTP
Sure, we love the friendship between Sheldon and Leonard, but this season's real BrOTP? Sheldon and Penny. Penny has learned to understand Sheldon in a way no one else can, and their friendship is wonderful (and funny) to watch as it continues to grow.

Weirdest Road Trip
The guys plan a suprise bachelor party for Leonard on The Big Bang Theory Season 3, which involves a van that once belonged to Richard Fenyman, one of Sheldon and Leonard's favorite physicists.

Somehow, Stuart became a character that become more creepy and more annoying as the season progressed. Sorry Stuart, but we really could have done without you this season.
10.
Favorite Guest Appearance
It's a tough decision, but the favorite guest appearance on The Big Bang Theory Season 9 is definitely Christine Baranski as Leonard's mother. And this season, her interactions with Penny were basically priceless.
11.
Funniest Quote
Then it's settled. Amy's birthday present will be my genitals.
Sheldon
Sheldon making the decision to finally have sex with Amy is a big deal, but of course, the way he says it makes it sound a little less glamorous. "Then it's settled. Amy's birthday present will be my genitals."
12.
Best Geeky Moment
There are so many fun and geeky moments on this show, but he best one of The Big Bang Theory Season 9 involves Wil Wheaton and a Star Trek uniform during the new Star Wars film. Bold move, Wil Wheaton. Bold move.
