Golden-Age and Silver-Age Batman. One issue of the original Detective Comics focused around the tale of Batman Jones, a child named in honor of the Dark Knight who rescued his parents, who in turn became a giant fanboy and tried desperately to join Batman and Robin in their adventures. (The only reason he stopped is because he found another hobby- stamp collecting) Even the iconic Joker was presented as nothing more than a clown with campy crime schemes. The Bronze Age and especially The Dark Age of Comic Books moved away from this, but the Adam West-era Batman and Batman: The Brave and the Bold certainly have their followings.
The Walking Dead: The Title Drop ("WE ARE THE WALKING DEAD!") that comes after a speech about how the survivors (or at least Rick, giving the speech, displacing some guilt) are Not So Different from the zombies. Extremely anvilicious, but nonetheless dramatic and effective.
Dark Empire: "Aren't I the master of all the Jedi? Your father was my apprentice." "Formless, I exist as pure energy. I am the dark side." Palpatine is just a huge ham.
When Green Lantern tried to give a sympathetic backstory to Dex-Starr, by all rights it should have fallen flat on its face. Dex-Starr's inherent comedy (he's a homicidal kitty-cat) should not mesh well with a tragic origin. It's not even a terribly good origin, it's standard "came from abusive family" stuff. But is something just terribly heart-wrenching about it that manages to make it work. "I good kitty."
The origin story is Batman in cat form, except without the "heir to the vast Wayne fortune" part: Dexter was raised from a kitten by a woman who was later murdered when some thieves broke into her house. He leads an increasingly desperate life as a stray until he's eventually placed in a bag, tormented, and thrown into a river. It just so happens that this was exactly the time when the ring forces were actively recruiting during the Darkest Night arc, and since the force behind the Red Lanterns is rage... And yeah, it's as Narm-tastic as it sounds, but it really works. Dex-Starr good kitty.
Many "relevant" and "edgy" Bronze Age stories like the Green Lantern / Green Arrow team-ups featuring the evils of drugs, poverty, racism, etc, are hilariously over-the-top, Anvilicious, and two-dimensional, but the fact that the stuff was ground-breaking at the time, plus the writers' complete sincerity about the sentiments expressed in the stories, save them from most of the contempt usually afforded to such preachy PSAs.
With just one overwrought line and goofily gaping expression, the issue 23 cover◊ of EC Comics' Tales from the Crypt manages to tell the most awesomely concise horror story ever...
LOCKED! I'm locked in this MAUSOLEUM with... with this THING!
In Doctor Strange: The Oath, a critically-injured and unconscious Strange has been carried through the doors of a hospital by his manservant Wong. Though they have obviously come in through a pouring rain, his Cloak of Levitation is at full billow. In fact, it has hooked around the crash bar and is holding the door open.
Watchmen: The words "exploding psychic teleporting squid alien" should never appear in the plan of any villain who expects to be taken seriously, but seeing how masterfully said plan was carried out and the horrific aftermath turns it into pure Nightmare Fuel.
