Okay, guys, I went to the Phineas and Ferb Meet and Greet and it was awesome!
Favorite part? When the director said "His name is Doof and we'll do what he says! Woop, woop!" XD
I do remember, after that was over, though, there was this part where you could hear over the speakers this little bit:
DJ: Hey, what are you doing here?!
Doofensmirtz: Ha ha ha! My name is Heinz Doofensmirtz and I've taken over this radio station! Now I will use it for evil purposes! And now, behold, a song that is guarenteed to get stuck in your heads forever!
Cue My Name is Doof
DJ: His name is Doof and I'll do what he says! Woop, woop!
Doofensmirtz: See? It works! It's the "Woop, woop", part!
Female Chorus: Perry!
Doofensmirtz: What?! Perry the Platypus?!
Cue Fight Scene, Doofensmirtz getting hurt while crashes are heard
Doofensmirtz: Looks like I won't be able to play the piano-
More fighting and other stuff
Doofensmirtz: CURSE YOU, PERRY THE PLATYPUS!
DJ: Thanks, semi-aquatic mammal!
