The Positive Negative Reaction

"The Positive Negative Reaction" is the sixteenth episode of the ninth season of the American sitcom The Big Bang Theory. The episode will air February 18, 2016.

Summary
Bernadette tells Howard that she's pregnant but his reaction is not what she thought it would be. The guys take Howard to a karaoke bar where Penny's Posse join them to celebrate.

Extended Plot
Bernadette sends Howard on a very small scavenger hunt with clues which lead him to learn that she is pregnant. Howard is overjoyed but then starts to panic as he begins to worry about the future and whether they'll make good parents.

Howard tells the guys and while Leonard and Raj instantly congratulate him, Sheldon immediately thinks that a baby will ruin all their fun activities. Leonard says there is enough room for two babies in the group and Sheldon immediately concludes Penny is pregnant. Sheldon is the other baby.

Bernadette starts to tell the girls, which Penny ruins it by blurting out a text she is reading off of her phone from Leonard. The girls quickly congratulate her and get excited about her baby. Bernadette is still upset that Howard wasn’t as excited as she thought he would be. Amy finally gets to join in their sex talk since she is no longer a virgin. Also, Bernadette admits that she conceived the baby while she and Howard were using Sheldon's bed which shocks Amy.

The guys take Howard to a tiki bar while Howard worries about his financial future. While Sheldon heads to the bathroom, the guys propose an improvement to a sophisticated guidance system. It was originally from an idea of improving a guidance system for drunks to keep them safe and on track. Drunk Sheldon returns after visiting the kitchen and validates their calculations. He also shares a moment with Howard about how they both grew up without their fathers but he knows Howard will be a great dad. Howard is now more excited about the baby.

While the girls continue talking about the news, they get a text from the guys to join them. From Sheldon's text, Amy knows Sheldon is drunk.

When the girls arrive, Sheldon immediately pats the empty chair next to him for Amy to come sit next to him and seems happy to see her. Leonard and Penny get a chance to quickly talk about whether they want to have kids. Not right away. Howard is finally excited with Bernie and apologizes. Raj and Leonard sing a Salt-N-Pepa song. Then Penny and Amy sing Justin Bieber’s song "Baby". Sheldon winks at Amy. Howard gets up and sings a touching “Havin’ My Baby” to Bernadette. Sheldon shouts at Howard about using his bed.
