Adult Sheldon: I tried to explain to my parents that a mutant named Cyclops, who shoots laser beams out of his eyes, helped me eat a licorice stick. Went right over their heads.

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: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

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?

Adult Sheldon: Just like that, I overcame my fear of choking. All that was left was my fear of dogs, birds, insects, germs, hugging, button fly pants, rivers, ponds, lakes, oceans, estuaries, corduroy, root vegetables, squeaky balloons, tinted windows, take a penny, leave a penny, fireworks, potbelly stoves, dust bunnies, that fuzz on peaches.

George Sr.: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

George Sr.: If we take him to a shrink, it feels like we're admitting something's wrong with him.
Mary: He hasn't had solid food in five weeks.
Meemaw: Well, if there is something wrong with him, it ain't constipation.
