Justin Hartley, who plays Oliver Queen, was signed to play Arthur Curry on The WB's Mercy Reef/Aquaman series. After the UPN/WB merging, The CW never picked up the series.

Clark: It's my mess, Mom, I need to clean it up.
Martha: You're not responsible for what happened. Zod is.
Clark: Zod would not have been released if for once in my life I had listened to Jor-El... and done what he asked me to do.

Lois: Hey, you guys are not gonna believe what just happened to me. I'm out there jogging along, minding my own business, when out of nowhere a barn door comes falling from the clear, blue sky and almost crushes me. How does that happen?
Clark: Maybe it fell from an airplane...
Lois: Good guess but the only thing out there was a severely traumatised sparrow.

Lois: Uh oh, does Clarkie have the sniffles?

Lois: Where did your barn door go?! It was here late last night when I came to drop off the documents and now it's gone.
Clark: Look at that, it is gone!
Lois: And it's been ripped right off its hinges. Oh my God, that barn door, I knew it looked familiar! Now, how in the world does that happen?

Chloe: What happened? Is everything all right?
Clark: I sneezed.
Chloe: And?
Clark: And? Chloe that's not normal.
Chloe: Well, Clark, nothing with you is exactly normal but I wouldn't call sneezing today's headline.

Clark: I tried to warn you, I've come down with some sort of cold.
Chloe: And become a walking air cannon!

Clark: It almost hit Lois!
Chloe: Lois as in Lane?
Clark: Now she's on a one-woman crusade to find an explanation. You know her, she won't stop digging until she hits China!

Lex: Well, I forgot what a concerned parent you are. That's why you're having me followed, isn't it? To make sure I don't destroy the rest of the world?
Lionel: If I were having you followed, son... you would never know it, I can guarantee you that.

Lionel: (to Clark) He might remember it all. Whoever his captors are, if they put enough pressure on him, he could tell the truth... about you.

Lex: Powers? I don't know what you're talking about.
Orlando Block: Oh, come on, Lex! We both know you were the one at the Pentagon, swatting away those bullets like they were mosquitoes! And not even a scratch.

Lois: It was sunny and seventy five, there was nothing extreme about the weather.
Chloe: Well, you might not have felt it, I mean, it was probably in the upper atmosphere but there must have been some sort of change in the barometric pressures.
Lois: Okay, either you've been watching a little too much Weather Channel or your year at the Daily Planet has turned you into a hardened skeptic.
Chloe: It's called being realistic, Lois, you might wanna try it once in a while.
Lois: You're the one who always told me that science can explain only a fraction of what happens in this crazy town.
Chloe: And this happens to fall into that fraction.

Chloe: Lois, what are you doing here?
Lois: I wanted to personally hand deliver this article to your editor.
Chloe: An article? You're a journalist now?

Lois: That barn door could've chopped me in half, read it.
Chloe: Funny, I don't remember there being an 'E' in 'tornado'.
Lois: Just a little typo.
Chloe: Mmhmm, and the extra 'H' in 'weather'?
Lois: You know what I think? I think that you're just a little bit jealous that you're not the only one in the family with a natural way with words!

Orlando Block: Now, you obviously did something to yourself... what was it?
Lex: Do you really wanna know? A being from another dimension... actually, another planet, inhabited my body and gave me powers. It sounds ridiculous but it's true.

Oliver Queen: Lionel, I'm involved in a lot of business ventures as you know but I can assure you... kidnapping is not one of them.

Lionel: I know, I know, Oliver, you've suffered through a lot in your young life but if you have so much as laid a hand on Lex, the word 'suffer' will take on a whole new meaning to you.
Oliver Queen: Sounds like a threat.
Lionel: Have a pleasant stay in Metropolis, Oliver. However brief it is.

Chloe: When you escaped from the Kryptonian Land of the Lost, I bet you didn't think that you'd be rewarded by having to save Lex Luthor while battling a raging head cold, huh?
Clark: Not exactly the goodbye gift I was expecting, no.
Chloe: I guess heroes don't get sick days.

Chloe: Clark, if your sneeze can blow a barn door seven miles across Smallville, I bet you anything you can take that one out no problem.
Clark: Chloe, I just can't force it.
Chloe: Why not? You can do anything.
Clark: Except sneeze on command! It's a reflex, not a circus trick.
Chloe: Then blow.
Clark: That's not funny.
Chloe: I'm not kidding. Clark, with a sneeze like yours, that says a lot about your lung capacity. Now, just take a really deep breath and blow it out as hard as you can.
Clark: That's a steel door, it's not a birthday cake.

Chloe: (after Clark blows the door down) Good thing you didn't have garlic today.

Orlando Block: (to Lana) Now, in case this stuff really does turn you into some kinda super chick, just remember, there's a gun pointed at your boyfriend's head the whole time.

Lois: Look, I swear, you guys, when I was writing that article, I dunno, I-I don't think I've ever been happier in my life. The thrill of discovery, the clacking of keys, the scent of fresh ink... yeah, I think I've finally found my calling.

Lex: Lana, those are just security cameras to ensure the safety of everyone in this property.
Lana: I see. Was I breaching security when I was alone in my bedroom?

Lana: Lex, the cameras go or I do.

In the scene where Chloe is holding the newspaper with the article titled "LEX LUTHOR DONATES MILLIONS TO REBUILD CITY," it is revealed after close examination that parts of the article are duplicated in the column on the right, which is supposed to be a different article.

Chloe: (after Clark sneezes) Gesundheit!

Gesundheit is generally said after a person sneezes to wish them good health.

Lex: (to Lionel) I hate to disappoint you but whatever powers I had are long gone. So, if you're looking for an encore performance, you're outta luck! Elvis has left the building.

"Elvis has left the building," was a phrase typically used after an Elvis Presley concert to disperse any lingering fans hoping for an encore performance.

Lionel: I suggest you concentrate on remembering every little, minute detail of that horrific day!
Lex: Well, I guess I should've kept a blog... because I suffered a total memory loss!

A blog (short for weblog) typically takes the form of an online diary but it can also apply to websites in general with dated entries.

Clark: She made a phone call to someone named Robert Pontius.
Chloe: The highest paid Sam Spade in Metropolis?

Sam Spade was a private detective in the novel and 1931 movie, The Maltese Falcon.

Chloe: When you escaped from the Kryptonian Land of the Lost, I bet you didn't think that you'd be rewarded by having to save Lex Luthor while battling a raging head cold, huh?

Land of the Lost was a TV series about a family of three trapped in an alien world that was broadcast from 1974 to 1976.

Chloe: Huff, puff and blow this door down!

This is a reference to the Three Little Pigs fairytale where the Big Bad Wolf would utter the phrase: "Then I'll huff and I'll puff and I'll blow your house down."
