Dean: Yeah, the whole Timmy-Lassie thing. Lassie was a Emmy-winning TV show based on a boy (Timmy), the profound connection between him and his collie (Lassie) and his ability to come to the aid of those in trouble.
Sam: You watch Oprah? The Oprah Winfrey Show is a long-running daytime talk show with many celebrity guests. The topics on the show are mainly geared towards women -- hence Sam's astonishment with Dean being familiar with the show.
Dean: Like Willard? 1971 movie (remade in 2003) about a lonely man who uses his unusual bond with the rats he lives with to exact revenge on the coworkers who put him down.
Creutzfeldt-Jakob Disease The victim is first diagnosed with Creutzfeldt-Jakob disease (CJD), which is a rare and uncurable condition that degenerates brain matter. It is also related to BSE, commonly known as mad cow disease, which is why Sam refers to CJD as "human mad cow disease".
Dean: (to Sam) You're like the blonde chick in The Munsters. Marilyn Munster was the blonde-haired, all-American member of the Munster family, a family of monsters, and therefore considered herself the freak.
The town of Oasis Plains is a fictional town in Oklahoma.
There is no Oklahoma Gas & Power. In reality, the workers in the teaser would be working for Oklahoma Gas & Electric (or OG&E) and their trucks would be orange.
In the shower death scene with Lynda Bloome (Carrie Genzel) at 14:50 to 15:30 minutes in, she gets attacked by spiders. First she starts to run and falls through the glass and the glass falls inward. Later when you see her dead on the floor the glass has fallen outwards, also when her blood falls it fell straight down with no moving splatter, just one straight blob.
About 2min 45 seconds into the show, as Travis is running to the hole, we can see the camera crew following him. Their shadows appear right below the sinkhole.
After Sam comes back out of the hole after trying to see what was down there, he doesn't have any dirt on his clothes, not even on his white shirt. There's no way he could have come out clean from that small, deep hole.
The timing of the episode's finale doesn't make any sense. It's clearly fairly early in the evening (no later than midnight) when the brothers get back to the PIke house. Everybody's awake and all, and the brothers were only about 60 miles away in daytime when they headed back. Then there are a few minutes of them holing up in the house, fighting the bugs, and then...it's sunrise.
Sam: Well, Dad never treated you like that, you were perfect. He was all over my case. You don't remember? Dean: Well, maybe he had to raise his voice, but sometimes you were out of line. Sam: Right! Right, like when I said I'd rather play soccer than learn bow hunting. Dean: Bow hunting's an important skill! Dean: Growing up in a place like this would freak me out. Sam: Why? Dean: The manicured lawns, "How was your day, honey?" I'd blow my brains out. Sam: There's nothing wrong with normal. Dean: I'd take our family over normal any day. Dean: Kinda hungry for a little barbeque. How about you? (Sam glares at him) What, we can't talk to the locals? Sam: And the free food's got nothing to do with it? Dean: Of course not, I'm a professional! Dean: Hunting's our day job. And the pay is crap. Sam: Yeah, but hustling pool, credit card scams. It's not the most honest thing in the world, Dean. Dean: Well let's see. Honest...fun and easy. (pause) It's no contest. Besides, we're good at it, it's what we were raised to do. Sam: Yeah, well, how we were raised was jacked. Dean: (after winning at gambling) Work, work work. No time to spend my money. Sam: Creutzfeldt-Jakob Disease. Dean: Huh? (confused) Sam: Human Mad Cow Disease. Dean: Mad Cow.... wasn't that on Oprah? Sam: You watch Oprah? (Dean looks embarrassed) Sam: The question is, why bugs and why now? Dean: That's two questions. Dean: Hmm...looks like there's only room for one. You want to flip a coin? Sam: Dean, we have no idea what's down there. Dean: All right. I'll go if you're scared. Scared? Sam: Flip the damn coin! Dean: Call it in the air, chicken. (flips coin) Sam: (catches coin) I'm going...don't drop me. Dean: (towel wrapped around his head) This shower is awesome. Real Estate Agent: We accept people of all races, color, and sexual orientation. Dean: Hmm, right. Ah, I'm going to go talk to Larry. Okay, Honey? (smacks Sam on the butt)
