The Wish (Buffy, Season 3)
We get to see an alternate reality where Buffy hasn't come to Sunnydale and things are REALLY fucked up, this includes Buffy's second death out of 3 I believe.
Band Candy (Buffy, Season 3)
Candy makes all the adults act like teenagers, hilarity ensues as well as Giles and Buffy's Mum getting it on, I need say no more.
The Gift (Buffy, Season 5)
Buffy dies, it's epic and bloody heartbreaking.
Smile Time (Angel, Season 5)
Angel gets turned into a puppet, the sheer genius of it is sometimes to much to comprehend.
Chuck Versus the Suburbs (Chuck, Season 2)
Chuck and Sarah going undercover as married couple in the suburbs, whats not to love?
State (Friday Night Lights, Season 1)
What an episode, bloody hell.
Tomorrow Blues (Friday Night Lights, Season 3)
Pretty much the beginning of a new era for FNL.
The Constant (Lost, Season 4)
It's a Desmond ep so you already know it's awesome but this one is especially fucking good, I mean the phone scene alone is enough to make it on this list.
Three Men and Adena (Homicide: Life on the Street, Season 1)
Admittedly I've only seen the first 3 seasons of Homicide, but episode in it's similarity to 12 Angry Men (being just set in one room) definitely leaves a mark.
Leave it to Beaver (Veronica Mars, Season 1)
Sometimes when you build up such a big mystery like they did in VMS1 the ending can be anti-climatic, luckily they managed to avoid and it made for one hell of a finale.
I Am God (Veronica Mars, Season 2)
An extremely powerful and well written episode, though I haven't seen it in a while. (god I'm just amazing at writing blurbs)
In the Beginning (Supernatural, Season 4)
Dean travels back in time to meat his young Mother who turns out to be a hunter, fuck yes.
Jaynestown (Firefly, the only season)
"We gotta go to the crappy town where I'm a hero" - you said it Wash, you said it.
Home (The X-Files, Season 4)
I don't know why but I love the disturbed, and this is the perfect example of that.
Motherboy XXX (Arrested Development, Season 2)
Proves why AD was leaps and bounds ahead of most other comedy shows.
Phase One (Alias, Season 2)
A massive game changer, plus that opening *drool*
