Calendar with Candace's birthday marked.
Phineas dashes out of bed.
"It's Candace's birthday!"
"Like the Venus De Milo,"
"...except she's not armless and handless."
"She's got a big, honking truckload..."
"...of ship-launching qualities."
"-is the reason she bears no..."
"-resemblance to a praying mantis!"
"Only wears designer sweaters!"
"She's got an allergy to dairy."
"And she's anything but ordinary!"
"This is yours, I believe?"
"Happy birthday, Candace."
"I made you a special breakfast."
"Please don't tell me we're going to Mt. Rushmore..."

"Okay, Candace. It's your birthday, you can pick out anything you want."
"Ah, I'm just here on the Mr. Slushy Burger worker exchange program."
"What are you girls doing here?"
"Fireside Girls field trip."
"He and Ferb are up at the monument,"
"Well, we could use a lookout."
"Now, where should we start?"
"Oh, Old Reliable Geyser. How exciting!"
"I'm just gonna go back to the gift shop."
"Mom! You gotta see what Phineas and Ferb are doing!"
"Uh, excuse me. Aren't you a little young to be restoring a national monument?"
"I found an absolutely brilliant parking spot."
"I found an absolutely brilliant parking space!"
