- Teal'c: Since it is their planet, is it not we who are the aliens?
- Dr. Daniel Jackson: Actually, the word alien refers to anything characteristic of a very different place or culture, anything really strange relative from our own perspective.
- Jack O'Neill: Think we call you alien because you're from Chu'lak? Ha.
- Dr. Janet Fraiser: [after traveling through the Stargate to help with a medical emergency] Now *this* is a house call.
- Jack O'Neill: [Jack and Daniel are in the infirmary. They have just had a major argument on a planet] Listen I, uh...
- Daniel Jackson: No, no. Um... sorry, you were gonna say...
- Jack O'Neill: No, it's just that, uh... Well... you know...
- Daniel Jackson: No I know, I know. I know. You know that I...
- Jack O'Neill: I know. It's obvious there's something...
- Daniel Jackson: Something, something wrong with us.
- Jack O'Neill, Daniel Jackson: Physically!
- Janet Fraiser: [enters] Well, there's nothing wrong with you.
- Daniel Jackson: What?
- Janet Fraiser: Well, I've run every test I could, short of exploratory brain surgery and you're both in perfect health.
- Jack O'Neill: Huh.
- Jack O'Neill: [trying to keep aliens quarantined] Get back. Come on, get back. Fine. Knock yourself out. Go ahead. Go play in the street. Forget your sun block.
- Dr. Daniel Jackson: Well, maybe you could try coming up with something better than inappropriate sarcasm.
- Jack O'Neill: You want sarcasm? Nice to meet you.
- Major General George Hammond: So, this inaudible sound was making you sick, but not in the same way that it was affecting the aliens? They need the sound to live, but we altered it by harming the organism that makes the sound?
- Jack O'Neill: Sounds right.
- Jack O'Neill: You're obviously misreading a basic philosophical difference of opinion on how to handle a crisis.
- Daniel Jackson: Oh please! We have a-a difference of opinion on just about everything!
- Jack O'Neill: Give me an example.
- Daniel Jackson: U-u-u, I don't know! Pick something! How - how about - how about mythology!
- Jack O'Neill: Rumors, lies, fairytales.
- Daniel Jackson: You see! See! See! See! See! See!
- [jumps around in a circle in frustration]
- Daniel Jackson: Mythology is one of the primary motivations for cultural development!
- Jack O'Neill: Maybe it is! What's that got to do with *filming a plant*!
- Daniel Jackson: Exactly!
- Jack O'Neill: What does *that* mean!
- Daniel Jackson: I don't know!
- [they silently look at each other]
- Jack O'Neill: [calmly] Okay. What was that?
- Daniel Jackson: I don't know. I don't feel so good.
- Jack O'Neill: I've got a headache.
- Captain Samantha Carter: [after a humanoid on PJ2-445, previously-confirmed as uninhabited, bends down and stares into the camera of SGC's crashed UAV] That would confirm the presence of life forms on the planet!
