Phineas Flynn: Okay, everyone, I think the tail is all set. I'll just go check with the foreman. Isabella Garcia-Shapiro: He's gone! Phineas Flynn: Hey, where's Perry? Did he really slip away? On his anniversary? Sometimes it seems like Perry's missed every single cool thing we've done all summer long. I guess he can do whatever he wants. After all, it's his day, right? [Perry stands behind the tree and throws a stone, which clatters to something] Baljeet Rai: Hey, what was that small noise? Phineas Flynn: Let's all go walk over to it!

Okay, everyone, I think the tail is all set. I'll just go check with the foreman. He's gone! Hey, where's Perry? Did he really slip away? On his anniversary? Sometimes it seems like Perry's missed every single cool thing we've done all summer long. I guess he can do whatever he wants. After all, it's his day, right? (STONE CLATTERS) Hey, what was that small noise? Let's all go walk over to it. Good morning, Agent P. A quick word. Recently you've been having some close calls and your host family has almost caught you sneaking into your lair several times. No need to remind you, but I'll do it anyway, that if your cover's blown, you'll have to be transferred to another city And we both know you wouldn't like that. I remember the day you were first assigned. Enjoy your platypus! Thank you, cheerio! Agent assignment complete, sir. Good job, Karl. If you keep up the great work, you'll make unpaid intern KARL: And I did.
