Pilot

Sam and Dean's mother dies under mysterious circumstances. Twenty one years later, Dean breaks into Sam's apartment, tells him he's looking for beer, and drags him off to nearly get killed by Casper. Then Sam's girlfriend coincidentially dies in the same way his mother did - she is beat to death by a plunger-wielding maniac.

Wendigo

Sam and Dean notice that the bears in Colorado are apparently extraordinarily hungry for human flesh. Thus, they set off and nearly get eaten by a Wendigo, at which point millions of viewers ask the important question: What the **** is that?

Dead in the Water Sam gets to grope hot naked women while Dean bonds with small children. Awwww. There was something in here about a dead kid that looked like he'd wandered out of The Grudge and his bicycle, but it's not terribly important in the grand scheme of things.

Phantom Traveller

Dean's secret weakness: not Kryptonite, polka music (though that might work) or women, but rather airplanes. There was something about demons in here too but the viewers were too busy laughing about Dean. The demon confesses that he knows the plunger-wielding maniac, for they belong to the same country club.

Bloody Mary

No longer just an urban legend! Now comes with a mirror and longer than ever nails! Collect all three models! This particular incarnation of Bloody Mary only claws out your eyes if you're guilty about someone's death. This apparently encapsulates half the population, including Sam and Dean. Sam is guilty about his girlfriend's death, as he believed he should have heard the sounds of Jess's brain being sucked out with a plunger. No one knows what Dean is guilty about, but he may have killed some girl because the sex was just that good.

Skin

Skin is about a shapeshifter that thinks Dean is hot and thus spends a lot of time pretending to be him. If you have sex with the guy you're borrowing a body from, is it masturbation? This question and more leads to confusion for Sam, the viewers, the Pope, and George W. Bush, who can't decide if it should be illegal. Anyway, at the end of the episode, fake Dean is killed by real Dean, unless it's the other way around. How would anyone know?

Hook man

The second of the episodes based off of urban legends. People keep dying and Sam and Dean trace it back to a crazy dead plunger-wielding priest. At this point Dean solves the problem the only way he knows how: he lights everything in sight on fire. This will be a continuing quest for him throughout the series. However, it will never lead to the characters getting caught.

Bugs

The first rule of the episode Bugs is that you do not talk about the episode Bugs. The second rule of the episode Bugs is that it doesn't exist. Non-existance is sponsored by The World's Shortest Night and Dean slapping Sam on the *** and posing as his boyfriend.

The Journey Home

Sam and Dean return home. Golly gee, I never would have guessed that from the title. They meet a hilarious woman named Missouri who threatens to whack Dean with a spoon. Dean doesn't look too opposed to this idea. Mary makes an appearance and the audience pretends to be surprised. She apologizes to Sam for something, possibly nearly burning him to a crisp. John hides from his pimp in Missouri's house.

Asylum

Sam finally gets counseling, and promptly attempts to shoot Dean, thus exposing the problems with the modern mental health field. Dean lights the body of an insane psychiatrist on fire, thus continuing his pyromaniac habit. Both characters violate the "never split up" rule of horror movies and it comes back to bite them in the ***.

Scarecrow

Despite the title, this episode in no way relates to The Wizard of Oz. Sorry. Joining the "Christians are ******* psychos" block is this "Pagans are also ******* psycho, let's all be atheists" episode. Dean and Sam have a huge fight and Dean gets nearly sacrificed to pagan gods in order to make the fields grow or something like that. Unlike the scarecrow in The Wizard of Oz, this Scarecrow is a representative of the god, as well as PSYCHO, and tries to kill people. It is also, in Dean's words, "fugly."

Faith

So Faith is about this guy who pretends to be healing people by faith, and he sort of is, except he's also killing people in return. And except for the part where it's actually his wife doing it. But in any event, the moral of the story is that only the show's creators have the right to decide who lives and dies. And maybe it's okay if fanfiction writers do it too.
