Penny: If you were to die this evening with no opportunity to communicate with anyone, what would you most regret not having told someone?
Sheldon: So, it would be today? Huh. Well, I suppose there's something satisfying about dying on my birthday.
Penny: Today's your birthday?
Sheldon: Yes.
Penny: Well, that's always been a secret. Not even Amy knows.
Sheldon: Well, I don't enjoy presents. And the thought of people jumping out and yelling surprise fills me with more dread than the words George Lucas Director's Cut.

Amy: If I may, I-I'd like to propose a toast. Um, thank you all for coming tonight. I know it's customary for the birthday boy to receive presents, but I feel like I got the greatest gift the day he was born.
Sheldon: Amy, that was lovely.

The perfect February 26th, sometime in the future

Beep… Beep… Beep

"Sheldon…Sheldon… wake up" a sweet voice came from the kitchen and he slowly open his eyes yawning "I'm coming" going into the kitchen he smile gently at his wife "Good morning" "Good morning birthday boy, breakfast is ready" "Smell good… French toast?" "Yep, with butter and syrup" "Uhm delicious" "Glad you like them" despite are passed many years they look into each other eyes deeply in love when a loud cough interrupts them and an 8 years old boy in a colorful shirt, with brown hair and light blue eyes much taller than his peers "Hello mom and dad, every year the same story, I don't believe in such celebration but for our family's sake, happy birthday anyway" "Thank you Stephen, I appreciate your effort" Sheldon cheers him with the vulcanian hand and Amy gives him a plate with French toasts. They hear some noise from the other bedroom "She is up, you two don't touch any decorations, they are perfect this way, especially the balloon" Stephen whines: "But Mom…". After a while a 3 years old little hurricane in a yellow pajamas with brown bob hair and green eyes "Daddy… Daddy… Happy birthday!" hugging Sheldon's back and clinging to his neck "thank you Ann" the little girl hands him a colorful drawing "This is for you!" "Nice work! Can you explain your drawing?" Ann answers enthusiastically: "That's what are you going to do today!" "Really, I can't see…" "Dad… Sheldon…" both Stephen and Amy glare at him "Oh yes, I get it! That one should be me in my superhero outfit, I suppose, and this is a wormhole!" "Yes Daddy, tell me your story!" "It's a special day for me, I want to do something memorable for the human kind, like go millions of years into the future where my towering intellect is used to save the last remnants of mankind from a predatory alien race…" Stephen rolls his eyes watching his mom "Yes, pretty catchy but Dad I have to go school" "Well, I'm almost ready to go work, I give you a ride… Ann are you happy to spend the whole morning with Daddy?" she leans down to give her a kiss on her forehead "Yes!" "Amy, I'm not so sure I can stay alone with her" "You have a towering intellect and you are a great father… you can do it" she leans to give him a peck on his lips "Hope you find your wormhole and have a good day" Sheldon smiles at her and adds: "See you tonight little lady" "I love you" "I love you too" Stephen snorting: "Oh please!"

As Amy and Stephen reach the front door, Amy says: "Don't touch the strawberry frosting in the fridge" "But Amy…."
