Ronnie: Be afraid. Be very afraid.
Seth Brundle: There was an old lady who swallowed a fly, perhaps she'll die.
Ronnie: If you SAW him, Stathis, if you saw how scared and angry and desperate he is.
Stathis Borans: I'm sure Typhoid Mary was a very nice person too when you saw her socially.
Seth Brundle: My teeth have begun to fall out. The medicine cabinet is now the Brundle Museum of Natural History. You wanna see what else is in it?
Seth Brundle: I think you're making a mistake. I think you really want to talk to me.
Ronnie: Sorry, I have three other interviews to do before this party's over.
Seth Brundle: Yeah, but they're not working on something that'll change the world as we know it.
Ronnie: They say they are.
Seth Brundle: Yeah, but they're lying. I'm not.
Seth Brundle: I was not pure. The teleporter insists on inner pure. I was not pure.
Ronnie: I don't know what you mean.
Seth Brundle: A fly... got into the... transmitter pod with me that first time, when I was alone. The computer... got confused - there weren't supposed to be two separate genetic patterns - and it decided to... uhh... splice us together. It mated us, me and the fly. We hadn't even been properly introduced.
Ronnie: Don't you get it? I am finally onto something that's big. Huge.
Stathis Borans: What? His cock?
Ronnie: Crude Stathis. Even for you.
