Phineas and Ferb The Movie: Across the 2nd Dimension
| Ferb imitates Perry's chatter |
| Phineas: (To Perry) Of course, Ferb and I knew exactly what to call you. Young Phineas and Ferb: Bartholemew. |
| Phineas: (To Perry) So, not only have you been leading a double life this whole time, but you sat there and let us help an evil scientist open an evil portal into an evil dimension. And you did nothing to stop us?! Ferb: Well, he did pee on the couch. |
| Phineas: You know, I used to think you couldn't spell "platypus" without "us". Ferb: Well, you can, but it would just be Platyp. |
| Whoa. Deja-vu-ish. |
| Well, we've had a lot of great days, but we only have one Perry. |
| Sings in Everything's Better with Perry, Summer (Where Do We Begin?) (his 2nd Dimension self sings it also) and Kick It Up A Notch. |
