Sheldon: My first bathroom attempt. Let's hope this goes well.
Mary: Let me know if you need help.
Sheldon: I think I'll be okay. It's just number one.
Mary: I'm here if you need me.
[After Sheldon closes the bathroom door:]
Sheldon: [o.s.] Mom, I can't get my zipper down!
Mary: I'm coming.
Adult Sheldon: I am not saying my mother and I had a codependent relationship.
Sheldon: [o.s.] Mom, I can't get my zipper up!
Mary: I'm on my way!
Adult Sheldon: But she did have a tendency to baby me, and boy howdy, was I okay with that.

Adult Sheldon: I've always enjoyed math word problems. Try wrapping your noggin around this one. A brilliant young boy named Sheldon is about to start college. He needs to get from his linear algebra class to his physics class, which is 822 meters away. If his stride is 23 inches long and he only has 10 minutes, how many steps would he have to take per minute to make it on time? It's a doozy, isn't it? Don't worry. I'll show my work. First, we must determine the maximum velocity achievable without breaking a sweat. Sweating is for jocks and those who are worried the jig is up.

Adult Sheldon: Presenting... "Sheldon Cooper's Top Five Sources of News From My Childhood". Number five: Star Trek Fan Club Magazine.
Sheldon: Mom, DeForest Kelley's favorite episode is "The Empath."
Mary: Good to know.
Adult Sheldon: Number four: the Weather Cube from RadioShack.
Man: [from device] The humidity is 90% with a dew point of 79.5 degrees.
Sheldon: Mom! The dew point is 79.5 degrees.
Mary: [o.s.] Okay.
Adult Sheldon: Number three: The MacNeil/Lehrer NewsHour. Such a great theme song.
Sheldon: [hums] Buh-buh-bum.
Adult Sheldon: Number two: Meemaw after a few beers.
Meemaw: It took a while, but we finally picked a new name for my bowling team: The Ball Busters.
Sheldon: Hey, Mom. Guess what Meemaw named her bowling team? The Ball...
Adult Sheldon: And the number one source of news from my childhood: the bulletin board at the train store. News about trains in a store full of trains. Yummy.
Sheldon: How did this not make The MacNeil/Lehrer NewsHour?

Adult Sheldon: Later that day, we had a graduation party for me and my sister. I don't normally care for parties, but this one wasn't so bad.
Mary: Who's ready for cake?
Missy: Me!
Dale: Hey, should we say grace?
Mary: Heck, yeah! Let's hold hands.
Meemaw: Oh, cool. Let's say grace.
Adult Sheldon: Dale invited Jesus to the party, and while he wasn't on my guest list, it was okay because it made my mom happy.
Mary: And bless our friends and family...
Adult Sheldon: In fact, it was the best graduation party I had ever been to, until the one we had for my son, Leonard Cooper.
All: Amen.
Missy: Cake!
Adult Sheldon: I wanted his name to be Leonard "Nimoy" Cooper, but Amy wouldn't let me.
Amy: Be happy I let you name him Leonard!
Adult Sheldon: Okay, okay!
Amy: Love you.
Adult Sheldon: Love you, too.

Adult Sheldon: The following day, I attended my sister's elementary school graduation. She didn't deliver a speech to me, but she did make eye contact while she sang "This Land Is Your Land."
Kids: [sing] From the Redwood Forest To the Gulf Stream waters This land was made for you and me...

Adult Sheldon: The next day, the local news showed up to interview me and my family, which may sound impressive, but this is the same local news that covered a potato chip shaped like Texas.

Adult Sheldon: I ended up using the class goggles that day and did not get eyebrow lice. But eight months later, I did contract a mild case of pink eye. Were the two events related? This scientist says yes.

Adult Sheldon: I was angry at my mother and needed more information. While she told me to go to my room, she didn't say stay there. Boy howdy, I do love a loophole.

Adult Sheldon: I was not alone in asserting my independence that day. This tiny slice of hot dog also seemed to yearn for freedom. But sometimes... freedom comes at a cost. In this case, a lowly disc of processed meat... ...would nearly tear my family apart.

Adult Sheldon: In every young man's life, there are milestones along the road to independence. Squashing one's very first bug.
Sheldon: Aah!
Adult Sheldon: Tending to one's own boo-boo.
Sheldon: Not today, germs. Not today.
Adult Sheldon: And preparing a favorite meal without one's mommy.

Adult Sheldon: After my other attempts to return to the trancelike state of anesthesia failed, I turned to something Nancy Reagan herself told me to "just say no" to. My mind-altering substance of choice was... chamomile tea. But not your grandma's chamomile tea. A highly concentrated super chamomile of my own making. All the relaxing power of 30 cups of chamomile tea packed into a teaspoon of calming sludge.
Sheldon: Sorry, Mrs. Reagan.

Adult Sheldon: If I was going to recapture my insight into a unified field theory, I needed to find a way to put myself back into an altered state of consciousness. Native Americans would sit in sweat lodges for hours to achieve this. I lasted a minute and a half. Self-hypnosis is another means of bringing stillness to the mind. [Sheldon screams] When it isn't giving you a heart attack! The whirling dervishes of Central Asia employ a repetitive spinning technique to achieve a trancelike state.
Sheldon: [retches, falls down]

Missy: You're having a tooth pulled, not having a baby.
Sheldon: If it can work for getting an eight-pound human through a birth canal, it can work for a tiny tooth.
Missy: Eight pounds? I'm never having kids.
Adult Sheldon: Fun fact: she ended up having four.
Missy: And if I do, I'm taking any drugs they'll give me.
Adult Sheldon: That part was true.

Adult Sheldon: It was turning out to be the perfect Saturday. The ice cream man had extra napkins. I had tons of homework. And I was about to enjoy an orange sherbet Push-Up, which was the only kind of Push-Up I could actually finish. Then it all came crashing down.

Adult Sheldon: Of all my many skills, one of the lesser known is my impressive ability to wait for things. I once stood perfectly still for 38 minutes because a bee was on my shoulder.
Sheldon: [blows, groans]
Adult Sheldon: I once waited four and a half hours to be released from a locker.
Sheldon: Hello? Anyone there? That's okay. I'll wait.
Adult Sheldon: And one time, when Dr. Sturgis was late for a lecture, I stayed longer than everyone.
Sheldon: Where are you all going?
Student: Professor's not here.
Sheldon: I can teach the class. I just need a box to stand on.

Sheldon: Dad, the university offered to pay for us to go to California! They're even putting us up in a hotel.
George Sr.: You're kidding.
Missy: We're going to California?
Sheldon: No, just me and Dad.
Missy: That's fair. I'm so happy for you.
Adult Sheldon: Sometimes sarcasm was laid on so thick even I could detect it.
Sheldon: Thanks!
Adult Sheldon: This was not one of those times.

Adult Sheldon: Growing up, I had an aversion to any type of group. For example, rock groups. I'll restrict my drug use to Rolaids, thank you. Group costumes. I'll tell you who really didn't have a heart: my mother, for making me wear a funnel on my head. But of all the groups I didn't like, by far the worst was...
Dr. John Sturgis: Group projects. [class groans] Yeah. You heard me.

Adult Sheldon: In case you're worried, Mabel and I did finally make it to Oregon, where I remarried and lived to the ripe old age of 41.

Adult Sheldon: The Clean Air Act required all new cars to be equipped with catalytic converters to combat air pollution. The first state to do this was California, which led Texans to say things like-
Peg: I hate California.
Adult Sheldon: And...
Peg: When will that place fall in the ocean? [hacks]
Adult Sheldon: While not everyone was happy about it, six years later, one particular Texan saw an opportunity to get rich quick.
George Jr.: Oh, man, I'm gonna get rich quick.

Missy: Mom, we're going to Chuck E. Cheese!
Mary: We're not going anywhere. It's almost your bedtime. Sorry, hon.
Missy: Well, all that matters is that I'm the winner.
Sheldon: Yes, you are.
Adult Sheldon: Actually, I was the winner. We spent the whole day doing everything I love: drafting contracts, arguing about rules, and most importantly, never leaving the house.
