Melissa Rauch chooses her favorite Big Bang Theory episodes

To commemorate The Big Bang Theory series finale, cast members were asked to select their favorite episodes. Ones that showed the evolution of Howard (Simon Helberg) and Bernadette's relationship ranked among Melissa Rauch's most-loved episodes. 

The Pulled Groin Extrapolation

Attending a co-worker's wedding, Leonard and Amy get to know each other better, while Howard and Bernadette spend the weekend with Mrs. Wolowitz.

What Melissa said: "I loved when I would get to imitate Howard's mother in conversation with Howard's mother. Carol Ann Susi (The OG Mrs. Wolowitz) was such a special and incredible woman and working with her was always such a wonderful treat."

The Re-Entry Minimization

Howard returns from space ... without the welcome he wanted.

What Melissa said: "Episode where Bernadette gets sick when Howard comes back from space. I loved playing both the physical and vocal comedy of this episode. You really see how much Bernadette loves Howard and how she wants to rally and be romantic with him now that he is back - even if it means blowing her nose in his face."

The Parking Spot Escalation

Sheldon and Howard battle over an assigned parking spot.

What Melissa said: "Bernadette and Amy getting involved in the argument between Howard and Sheldon shows how much they love their significant others. It was so much fun playing this fight out. I'm so the opposite of Bernadette as far as her aggression goes, so it always feels nice to step into her confrontational loafers. And girl's night's episodes are always so much fun to shoot with Kaley and Mayim."

The Troll Manifestation

An online troll rips Leonard and Sheldon's published physics paper, so the guys rally to defend the two and expose the bully, while a girls night out leads to Penny, Amy and Bernadette dishing about embarrassing past events.

What Melissa said: "The Miss California Quiznos episode. Two words: The. Hair."

The Holiday Summation

Sheldon and Amy visit Leonard and Penny for the first time since the holidays and share details about their terrible trip to Texas.

What Melissa said: "In this episode Howard and Bernadette are adjusting to life with a newborn and them dealing with all the crying (mostly their own). I love how it shows them navigating this new life change together. When Howard says "Good job, Mommy" through the crib slats, I get teary every time."
