When Lawrence accidentally sells Candace's doll to Doofenshmirtz, Phineas and Ferb become detectives to try and find it.
"You were a sub-standard dad..."
"But when I look at this thing..."
"I grew up hearing your evil scheming down the hall."
"At my first ever swim meet..."
"You stepped on the other team's feet.."
"At my recital, you clapped louder than you should".
"But when you taught me how to drive...We actually made it home alive..."
"I guess it's possible that not every part of you isn't good..."
"I know at times I would cringe..."
"Like when you wore all that fringe."
"Or when you went out of your way to catch that foul ball."
"Makes me finally understand..."
"Maybe you're not so bad a dad..."
"Aren't you a little young to know about all these old detective shows?"
"Time to find out what this bad boy can do."
"...it's not even evil, much less illegal."
"Yeah, we can build on this."
