Peter Mann: Leonard, have you ever seen anything like this before?
Leonard: Why you asking me if I've seen some shit like this before? Do I look like I've seen some shit like this before? Hell, no I a'int never seen no shit like this before. Who the fuck would wanna climb up one of these walls and hang one of these? Musta been a big elephant-ass motherfucker.
Josh: This is what I love about my job. I get to travel, see the world, meet new cultures. I mean, it's all bacterial, but, hey, what the fuck?
[on insect's inner motivation]
Dr. Gates: Can I eat it or will it eat me?
Dr. Gates: [to Susan] So... you think your little "Frankenstein" has gotten the better of you?
Susan Tyler: Sometimes an insect will evolve to mimic its predator. A fly can look like a spider, a caterpillar can look like a snake. The Judas evolved to mimic its predator... us.
Leonard: You better tell me, what the hell is going on around here?
Susan Tyler: When I increased the Judas's metabolism, I must have sped up its breeding cycle. I mean, we're talking tens, hundreds of thousands of generations, who knows how many mutations...
Peter Mann: I don't get it, I just don't fucking get this. How could the Judas evolve into this?
Susan Tyler: Think generations, not years, okay. It took only 40,000 generations for apes to turn into humans.
Peter Mann: So?
Susan Tyler: We changed its DNA, Peter! I mean, we don't know what we did!
