Sheldon: Since when is it Pancake Sunday?
Mary: Since today.
Sheldon: No, it's not. It's Kellogg's Bran Buds Sunday, like it's been for the past three years.
Mary: Well, I thought it would be fun. I'll- I'll make you any kind of pancake you want.
Sheldon: On Bran Buds Sunday?
Mary: Fine. I'll put Bran Buds in the pancakes.
Sheldon: That could work.
[cut to Mary watching Sheldon eat at the kitchen table:]
Sheldon: [mouth full] It doesn't work. [spits out food]

Mary: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Principal Petersen: Our next young speaker needs no introduction, but that didn't stop him from writing one and making me read it. [laughter] "Fun fact." [audience groans, murmurs] I hear you. "The word 'valedictorian' is from the Latin 'valedicere,' meaning 'to say farewell.' It is primarily used in the United States, Canada, the Philippines and Armenia." Maybe that fact's more fun in Armenia. Please welcome your valedictorian, Sheldon Cooper.
Mary: Yay, Shelly!
Sheldon: Hello. I'm not very comfortable speaking in front of crowds. But there's a technique to reduce stage fright by focusing on one person in the audience and delivering your speech just to them. That's what I'll be doing today. If it weren't for this person, I wouldn't be here right now. They've taught me a lot, and it's by their example that I found the courage to move forward into this new and exciting chapter of my life. Missy... ...this is for you. Change can be scary, but I know we're going to be fine... ...because like you said, "It's okay to be scared. We just have to do it anyway." So if any of my fellow graduates are nervous about the future, know that you're not alone. I suggest you all try to be as brave as my twin sister. That's my plan. Missy, I wish I could give you advice about middle school, but I was so smart, I skipped it. If you make it to high school, we'll talk. Thank you. [applause]

Mary: You understand that some people are going to be intimidated by you, because of how smart you are?
Sheldon: Or maybe they'll recognize my intellect and make me their leader.

Sheldon: Mom.
Mary: [wakes up] What is it, Sheldon?
Sheldon: I know you had some questions about Star Trek, so I've compiled a detailed guide outlining all the shows, characters, and how they fit in a timeline.
Mary: Can we do this later? I've got a headache.
Sheldon: Unfortunately not. If we don't do it now, you'll be completely lost when we watch The Animated Series this afternoon.
Mary: Just 20 more minutes.
Sheldon: Mom, this is almost a hundred pages. We have to get started. In the 23rd century, alien races from around the galaxy have come together to form the United Federation of Planets, which is... open your eyes... Headquartered in San Francisco.

Dale: I was trying to convince your mom to go fishing with me.
Mary: Oh, fishing, that could be fun.
Meemaw: I ain't going fishing. I'd go to a flea market.
Mary: Oh, I do love a flea market.
Dale: Eh, I don't want to buy some dead guy's pants.
Mary: Oh, the outlet malls are still having their holiday sales.
Dale: I'd rather die and have you sell my pants at the flea market.

Dale: [sighs] All right, well, let's break it down. If you don't go on the date, Mandy might be upset with you.
Georgie: Right.
Dale: But if you do go, you might feel guilty.
Georgie: Right, but if I don't go, the new girl's gonna get stood up, and she'll be mad.
Dale: Georgie, you can't live your life afraid that women are gonna get mad at you. It's just what they're born to do.
Georgie: Makes sense.
Dale: I'm not a woman. I'm mad at you right now.
