Amy, Sheldon and Stephen are going to the beach. After getting there, by train, Stephen gets excited, claps into his hands. Amy carries him, so he would not run across the street.
Amy: Guys, I need to go to the restroom. Why don't you just sit here and wait for me? I will be quick. She lets Stephen sit on the little wall that separates the street from the beach. Sheldon sits next to him.
Amy: Here, I have a peanut butter and jelly sandwich for you. Eat that. I will be back in a few minutes. Are you alright, honey? Daddy will be here.
Sheldon smiles: Of course I will. If Mommy wants to miss out some of our guys' fun, it's her bad, right?
He winks, and Stephen smiles.
Amy: Keep an eye on him, Sheldon. Or Stephen, keep an eye on Dad.
Stephen giggles and bites into his sandwich. While Amy walks to the restrooms, Sheldon's phone chimes, he takes it out of his pocket and reads.
Sheldon: Kripke. Oh you….He is typing angrily, while a pigeon lands next to Stephen.
Stephen looks shocked at it. A gull looks at him, comes closer. He tries to move closer to his father, holds his sandwich into his dad's direction. Another gull lands on Stephen's other side, between him and Sheldon. It coos, and tries to take a bite while a third gull tries to land on Stephen's head. Stephen starts crying and runs towards the water. The birds fly away, and Sheldon finally looks up from his screen.
Sheldon panics : Birds!!!
He runs into the bathroom direction, when Amy comes back.
Amy: Sheldon, where are you going?
She goes to Stephen, who sits crying in the sand.
Amy: Honey, are you alright? What happened?
Stephen sniffs: No birds. Bad birds.
Amy: Did they want your food?
Stephen nods. Amy lifts him up, carries him to the bathroom.
Amy: We will throw that away if they touched it. Normally, you should not do that, because birds should find their own food in nature and not be dependent on people and their waste, and we produce too much waste anyway, but now we will make an exception.
Amy takes the sandwich and puts it into the trash can.
Amy: I have another one for you, okay? Don't be afraid of birds. Not all of them are like that. Most of them are very beautiful. I will take you to the zoo one day, where you can meet the nice ones. Not everyone of one species are alike. Try to calm down. Breathe slowly. Do you feel better?
Stephen nods.
Amy: Now lets try to find your dad.
Stephen squeaks: Hide and seek.
Amy: Yeah, let's see if we find him.
She puts Stephen down to his feet. He runs to the men's room where Sheldon stands in the middle, looking anxiously around, having his arms close to his body.
Stephen: Found you.
Sheldon picks him up and carries him outside to Amy.
Sheldon: I have no idea how anyone can use these. Germs are omnipresent, and it smells like…
He wrinkles his nose.
Sheldon: This place is so filthy. Just like these birds.
Amy: Why did you run away and leave our son alone? I told you to watch him. What if anything had happened? Why did you even let these pigeons get so close to him?
Sheldon: Kripke wrote me. I had to reply. It was just a second. He is a …
Amy: Not in front of Stephie. I don't want to know what Kripke wrote. You have to be there for your son. You could have checked your phone later.
Sheldon: But it rang.
Amy: You are a father now, Sheldon. You are responsible. I love your quirks, but sometimes I wonder how you can be so smart and still often don't realize what is most important. Now, give me Stephie. Come here, baby.
Sheldon gives Stephen to Amy.
Amy: What do you think we will go home now and watch Sesame Street?
Stephen: Yay.
Amy: They have Big Bird, which is a nice one.
Stephen: Yay.
Amy: And no chicken like your father.
Sheldon: Hey. I am no chicken. Birds are...
Amy: They make you turn into the Flash? Like running faster than you ever thought you could?
Sheldon: Exactly. I am a superhero.
Amy to Stephen: If he was a superhero, he'd be Super Chicken.
Stephen giggles.
Sheldon: If I have to be a bird, I'd be BirdMan.
Amy: You won't win this, Sheldon.
Sheldon: I think I did win, as always. We are going back home, where there are no birds, except the ones we watch on TV.
Stephen: Big bird.
Sheldon: Yes. Big bird.
Stephen laughs: Daddy is Big Bird Chicken.
Amy smiles, Sheldon sighs.
Sheldon: This was definitely the last time you convinced me doing something filthy.
Amy: You might be smart, but I have studied your brain, my love. I know how to trick you. It's my female super power.
Amy smiles, Sheldon looks irritated.
Stephen: My parents are superheroes. Big Bird Chicken and Brain Power.
Sheldon wants to say something, but Amy puts her index finger on his mouth.
Amy: Let's have Stephen the last word. He is a smart boy. Maybe we should make another one...
