Jim Parsons chooses his favorite Big Bang Theory episodes

To commemorate The Big Bang Theory series finale, cast members were asked to select their favorite episodes. For Jim Parsons, episodes that feature Sheldon's fears -- birds, public speaking -- were the cream of the crop, especially when he got to work one-on-one with his castmates.

The Luminous Fish Effect

Sheldon's getting fired forces him to explore what life has to offer outside physics, leaving Leonard to take drastic action to snap his friend out of his funk.

What Jim said: "There are many things about this episode that I like, but I picked it for one reason and one reason only: it is the first time I had the chance to meet and work with Laurie Metcalf, which was a dream come true."

The Adhesive Duck Deficiency

With the rest of the gang off on a desert camping trip to view the Leonid meteor shower, Sheldon must play hero after Penny slips in the tub and dislocates her shoulder.

What Jim said: "Kaley and I had some of our very best times on this show doing Sheldon and Penny scenes and this episode was full of them. From the awkwardness of Sheldon helping Penny get dressed, to the inappropriate way Sheldon helps Penny fill out her hospital forms, I can still vividly remember working on these scenes, even nine years later."

The Pants Alternative

Sheldon's fear of speaking in front of large groups threatens his ability to accept an award, so the gang tries to help him get ready for the big night.

What Jim said: "I loved how I got to work in one-on-one scenes with each of the other characters, that was a lot of fun. The big scene at the end, which may LOOK like a lot of fun, was actually very stressful: learning that Element Song nearly put me over the edge, mentally!"

The Agreement Dissection

Priya uses her legal expertise to rip apart Sheldon's roommate agreement, and the women take the flustered Sheldon out dancing.

What Jim said: "I loved the structure of this episode, the way I got to sort of take part in two different story lines: girls night and the fight over the roommate agreement at home. It was also a really fun episode with Mayim."

The Ornithophobia Diffusion

Sheldon must overcome his fear of birds.

What Jim said: "This was an absolutely absurd idea that our writers handled beautifully. Sheldon’s heartbroken desperation when the bird flies away was a genius idea that still makes me giggle when I think of it."
