Season One - 'Faith'
Season Two - 'In my time of Dying'
Season Three - 'Red Sky at Morning'

That was kind of fun! lol!!!

S1- Hell House
S2- All Hell Breaks Loose 1
S3- Mystery Spot (all-time fave!)
S4- It's a Terrible Life
S5- Swan Song (so far; I still haven't seen the first half of S5!)

At the moment my list is;

Season 1; Hell House, Faith
Season 2; Folsom Prison Blues, Playthings
Season 3; Bad Day At Black Rock (my FAVE), Malleus Maleficarum
Season 4; Yellow Fever, Heaven and Hell
Season 5; Changing Channels, Sam Interrupted and My Bloody Valentine- I can't choose!

Okay here we go lol:

Season 1: Pilot, Faith

Season 2: In My Time of Dying, Croatoan, Born Under a Bad Sign, Folsom Prison Blues (I couldn't narrow it down to two)

Season 3: Bad Day at Black Rock, A Very Supernatural Christmas, Mystery Spot

Season 4: Lazarus Rising, Yellow Fever, Death Takes a Holiday, On the Head of a Pin, The Monster at the End of this Book, The Rapture

Season 5: The End, Changing Channels, Abandon All Hope, Dark Side of the Moon, 99 Problems, Point of No Return, Hammer of the Gods, The Devil You Know, Two Minutes Till Midnight, Swan Song

Season 5 was to hard to narrow down but they were like all so good and worthy to be my favorites.

OK, well first of all, i haven't seen season 5, i'm somewhat ( a few months) new to the fandom and i didn't want to start season 5 in the middle without seeing the other seasons first so this re-airing of season 5 on the CW will be my first time seeing it.
ANYWAY!!
Fave episode of Season 1:"Hell House" It's when we first see the Ghostfacers, who, despite their extreme lameness, are FRIGGIN HILARIOUS. Go watch their online episodes if you haven't already. But that's not even why, it's the towel shot of Sammy, does it get any GREATER for a fangirl than that?

Season 2: "Nightshifter" because, of what i have season (seasons 1-4 in their entirety) i have yet to come across a better scene than Sam and Dean escaping in SWAT suits to "Renegade" by Styx. Best soundtracking EVER!! Though 'Tall Tales' is friggin HILARIOUS too.

Season 3: This one was ALMOST hard, but being a huge Sam Girl i have to pick "Bad Day at Black Rock." That whole episode was just... oh it was great. Jared really got the chance to be HILARIOUS in it, slapstick comedy, when done right (which Jared does it right) is the GREATEST. 'The Kids Are Alright' and 'Mystery Spot' are close seconds for opposite reasons, Chibi!Dean(Aka Ben, not to be confused with Wee!Dean) is hands down the greatest single-episode character and 'Mystery Spot' just... had me in tears the entire time. Poor Sam!

Season 4:Ahhh! So many good episodes! I have to pick "Yellow Fever" just because the Dean humor in it is friggin phenomenal! "And take a left hand turn in to oncoming traffic? I'm not suicidal!" God i love that. And how he suddenly is afraid of 4th floor rooms. But of course there's also "Monster Movie," which the mock cheesiness in it is just so great and of course there's "It's A Terrible Life," Come on, Smith&Wesson? That's just brilliant. And 'Wishful Thinking,' maybe i'm morbid but what's better than a 7 foot suicidal teddy bear???

And like i said, i haven't seen season 5 yet. i'm starting it this thursday.

My favorites are:

Season One
- The Pilot
