Farscape tried to have fun with the titles, usually goofing on movie titles. A few creative ones were:
**Back and Back and Back to the Future
I, E.T.
Rhapsody in Blue - creative if you know it’s about Zhaan
Bone to be Wild
The Way We Weren’t
The Maltese Crichton
A Clockwork Nebari
Lava’s a Many Splendored Thing
A Prefect Murder
Fetal Attraction
Hot to Katratzi **
Yeah all of Seinfeld episodes except one started with “THE”
The exception was “Male Unbonding” it was the 4th episode of season 1. It’s the one where Jerry’s childhood friend Joel makes him sick and he wants to end the friendship.
I don’t know why it amused me so, but it did. Last night’s episode title was “Inglorious Bassterds”. Maybe because anyone with the name Bass on that show is a total “terd”! 
Anyway, the Drew Carey Show early on had a lot of chemistry themed titles, but they found it too hard to think them up so they stopped.
Degrassi: the Next Generation has, for the past seven seasons, mostly used only ‘80s song titles for its episodes. Pass the Dutchie, Careless Whisper, Wanna Be Startin’ Something, West End Girls, I Still Haven’t Found What I’m Looking For, and so on. Presumably a nod to the original series’ '80s origins.
Slings and Arrows, a show about a theater company focusing mostly on Shakespeare, primarily used quotes or references from Shakespeare in its titles … and in particular, since each season focused on the troupe’s production of a specific play, each season’s titles related to whatever play was in production during that season.
**Frasier **did a lot of movie-based titles:
A Tsar is Born
An Affair To Forget
Crane vs. Crane
Death Becomes Him
Desperately Seeking Closure
Dial M For Martin
Frasier Crane’s Day Off
Guess Who’s Coming To Breakfast
High Crane Drifter
How To Bury a Millionaire
Morning Becomes Entertainment
My Coffee with Niles
My Fair Frasier
Roe To Perdition
Semi-Decent Proposal
Something About Dr. Mary
The Apparent Trap
The Dog That Rocks the Cradle
The First Temptation of Daphne
The Great Crane Robbery
The Last Time I Saw Maris
The Unnatural
The Wizard and Roz
Three Days of the Condo
To Kill a Talking Bird
War of the Words
“Supernatural” seems to be doing something (as you can see from this list), but I’m not sure exactly what. Classic song titles plus take-offs of book titles? I have to say, I love, “Are You There, God? It’s Me, Dean Winchester.” (And its companion, “It’s The Great Pumpkin, Sam Winchester.”) 
We’re going through the old “Star Trek” original series on dvr, editing them and titling them, and I have noticed that they had some of the most awesome episode titles in the history of television - The Naked Time; The Enemy Within; Dagger of the Mind; This Side of Paradise; The City on the Edge of Forever; A Private Little War; etc.
Showtime’s excellent series “Brotherhood” had a different them each season.1st season was bible verses, 2nd season was Bob Dylan lyrics, and the last season used Shakespeare quotes.
Grey’s Anatomy uses song titles for each episode.
Something they did for Breaking Bad, which I thought was quite awesome, was that every episode title from Season 2 in which the episode began with a pink teddy bear floating in a pool, spelled out what that scene was about, and what happened in the finale: Episode 1: 737, Episode 4: Down, Episode 10: Over, Episode 13: ABQ.
“737 down over ABQ”
Let’s not forget one of my very favorite titles for anything, ever: For the World Is Hollow, and I Have Touched the Sky.
They even had one called “My Bloody Valentine”, a bomb of a movie that Jensen Ackles, star of Supernatural, was in.
They also have the single best episode title of any episode in any show:
I can’t believe that I know these, but:
iCarly episodes all begin with a lower-case “i”:
“iScream on Halloween”, “iSpy a Mean Teacher”, etc.
Hannah Montana episodes are all parodies of well-known pop song names:
“I Will Always Loathe You”, “Don’t Go Breaking My Tooth”, etc.
I’m so ashamed.
Ah, yes, that was lovely. It goes right along with their ongoing meme of “Angels are dicks.”
Oooh, that’s a good one too, Maggie.
OOOOH!!! I know this one.
Ellery Queen!
My Bloody Valentine had the single most disgusting scene I have ever seen on a TV show, ever.
Criss Angel is a Douchebag does not actually refer to the magician Criss Angel at all. It’s about a guy that’s obviously supposed to be an imitation of him, but the episode never mentions the name ‘Criss Angel’ even once. The title is just a pointless putdown.
Sometimes I think that the fine people at the CW are not paying very much attention to what they get up to on Supernatural at all. They’re too busy with their silly teen shows and America’s Next Top Model to realize they have a show that calls god a dick, mocks people with their episode titles, and shows people eating each other alive.
(I think I have a pretty high grossout threshold, but they really went over it with that scene. I had to watch through spread fingers.)
Castle, the Nathan Fillion show about a mystery writer, has episode titles that either are real, or sound like, cheesy mystery novel titles.
“Home Is Where the Heart Stops”
“Deep in Death”
“Love Me Dead”
“The Fifth Bullet”
My favourites are the recent two parter:
“Tick, Tick, Tick…”
“Boom!”
A lot of Star Trek episodes from the various series reference titles of episodes from previous Star Trek series.
How can it be pointless when I enjoyed it soooo much? 
And I like it that way!
In Community, all of the episode titles except for the pilot are structured like a college class title. For example, there’s “Spanish 101,” “Advanced Criminal Law,” “Introduction to Statistics,” and “Debate 109.”
…I bet they’d notice fraternal incest, though.
Much to the chagrin of the filthy-minded fangirls.
Who you calling a filthy-minded fangirl?
