It’s Always Sunny in Philadelphia’s titles usually tell you exactly what’s going to happen in that episode. “Dennis and Dee Go on Welfare” “The Gang Finds a Dumpster Baby” “Dennis Looks Like a Registered Sex Offender” And they have title cards at the beginning of each one, after the cold opening.
One of the IMO best was the specific episodes of Breaking Bad Season 2 that showed the flash-fowards of what was to come in the finale.
You’d see the eye in the pool, the burning Teddy bear, etc. If you take the episode titles of just those episodes, they explained what was going to happen: “Seven Thirty-Seven” “Down” “Over” “ABQ”
All of the episodes of The Young Ones had one-word episode titles (“Demolition”, “Interesting”), except the final episode, “Summer Holiday”.
Every episode of I’m Alan Partridge was titled for a well-known film, but with “Alan” in the title (“Watership Alan”, “I Know What Alan Did Last Summer”).
I liked the one when the cold opening was Dee talking about her new boyfreind and the gang arguing about whether or not he was retarded. It ended with her saying “My boyfriend is not retarded” and then the title came up “Dee Dates A Retarded Person”
King of the Hill didn’t do this for its whole run, but for several seasons all the titles were puns based on movie/book/song titles, ie The Substitute Spanish Prisoner, Of Mice and Little Green Men, Beer and Loathing, My Own Private Rodeo, Full Metal Dust Jacket, An Officer and a Gentle Boy, The Miseduction of Bobby Hill, etc.
True Blood often (if not always) names its episodes after the songs (usually blues or country rock, sometimes jazz, almost always something fairly obscure) that it plays during the closing credits.
This is a long-standing formula for thrillers, especially by novel-mill authors like Ludlum. The adjective often comes from some proper noun, and the head noun usually is of Greek or Latin origin, or at least a word that’s otherwise associated with official things like law, government, etc.: The Odessa File, The Pelican Brief, The Bourne Conspiracy, The Hades Factor, The Janson Directiveand so on, ad nauseum.
No Ordinary Family uses “No Ordinary [something]” for all its episode titles. The first episode was “No Ordinary Pilot”. Other episodes include “No Ordinary Ring”, “No Ordinary Friends”, “No Ordinary Anniversary”, and “No Ordinary Sidekick”.
It started out as Sondheim titles, then it became musicals in general (but usually Sondheim), and then it became lines in songs in musicals (again usually Sondheim).

The episodes of Bottom are named to line up together with its own title, i.e. 'S Up, Burglary, Accident = Bottom’s Up, Bottom Burglary, Bottom Accident.
I’m ashamed to have to say this one, but no one else has (because no one else is watching), but The Mentalist episodes all contain some form of the color red (or a reference to something red) in their title.
