Adult Sheldon: The thought of spending an afternoon with Paige seemed excruciating, but I wanted to make my mother happy. I was torn.
Dr. McCoy: The release of emotions, Mr. Spock, is what keeps us healthy Emotionally healthy, that is.
Adult Sheldon: Luckily, the wise words of Gene Roddenberry flatly delivered by Leonard Nimoy resolved my dilemma.
Mr. Spock: That may be, Doctor. However, I have noted that the healthy release of emotion is frequently very unhealthy.
Adult Sheldon: I realized if Mr. Spock could rise above his emotions while the fate of the Enterprise hung in the balance, certainly I could tolerate Paige for a few hours.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: No, it was good.
Missy: Stay out of my life.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

Dr. John Sturgis: See, this is why we're great together. You teach me about social etiquette, and I teach you about beaver anuses.
Meemaw: [CHUCKLES] It is magical.
Dr. John Sturgis: Did you know "ani" is also acceptable as the plural of "anus"?
Meemaw: And the magic continues.

Dr. John Sturgis: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

Adult Sheldon: Not since sharing a uterus with my twin sister have I been so unhappy sitting next to someone.
