Quotes
"(Moses flees to the outskirts of Egypt. Rameses follows him on his carriage.) (Rameses: Moses! Moses! [drives his chariot in front of Moses to stop him. Moses just walks around it.]) Let me go! (Rameses: No, wait!) You saw what happened-- I just killed a man! (Rameses: We can take care of that! I-I will make it so it never happened!) Nothing you can say can change what I've done! (Rameses: I am Egypt! The morning and evening star! If I say, "day is night", it will be written! And you will be who I say you are. [places his hands on Moses' shoulders to stop him] I say you are innocent.) (Moses shoves Rameses away) What you say does not matter! (sighs) You don't understand. I can't stay here any longer! (Rameses: Moses...) NO! All I've ever known to be true is a lie! I'm not who you think I am. (Rameses: What are you talking about?) Go ask the man I once called "Father." (turns, walks away) (Rameses, on the verge of tears: Moses? Please!) (Moses sadly gives Rameses one final look in the eye) Good-bye, Brother. (turns and runs into the desert) (Rameses: Moses! MOSES!)"

Flea: We'll be the best circus act in the business!) (Princess Atta: You mean, you're not warriors?) (P.T. Flea: Are you kidding? These guys are the lousiest circus bugs you've ever seen! And they're gonna make me rich!) (Thorny: You mean to tell me that our entire defensive strategy was concocted by clowns?!) (Francis: Hey, hey, hey, hey. We really thought Flik's idea was gonna work.) (The fireflies put the spotlight on Flik) (Francis realizing his mistake: Oops.) (Princess Atta: Tell me this isn't true.) No, no no ,you don't... (Mr. Soil: This couldn't have happened at a most inopportune time. The last leaf is about to fall!) (Dr. Flora: We haven't collected any food for the grasshoppers!) (Thorny: If Hopper finds out what we almost did...) (The Ant Queen: Hopper is NOT going to find out. We're going to hide all this and pretend it never happened. You bugs were never here, so I suggest you all leave.) But the bird! The the the bird will work! (The Ant Queen: I never thought I'd see the day when an ant would throw himself before the rest of his colony.) What? (The Ant Queen: Point is, Flik, you lied to us.) No, no, no, no! I just... (Princess Atta: You lied, Flik. You lied to her. You lied to the colony. You lied to ME! And like an idiot, I believed you.) I..I..I. I was just afraid, if you'd known I'd gotten circus bugs...I..(sighs)... I just wanted to make a...difference. (Princess Atta [sternly]: I want you to leave, Flik. And this time...don't come back. (Dot gasps at her sister's actions; The Queen's pet aphid lets out a very sad whimper. Flik hangs his head and turns to leave with the circus bugs) (P.T. Flea: Tough crowd..)
