The Batcycle is several hundred feet away when Dove and Eagle-Eye spot The Dynamic Duo coming and Eagle-Eye says in a normal tone of voice that he's seeing ghosts. Somehow Robin hears him despite the distance when he jumps out to punch them.
Batman bets Robin that the street corner holdup that Penguin foils is a charade. They don't seem to be sure, but the man committing the robbery is Dove, one of Penguin's henchmen that they fought earlier. Dove is even wearing the same outfit and helpfully has his name emblazoned on his chest, but they still don't recognize him.
Goof: Batman says he has a camera in the Batmobile which might suggest an interior mounted camera, but the footage he watches is filmed from the exterior of the vehicle and beyond the vehicle.
Chief O'Hara: (After Batman and Robin have been gunned down) Don't feel too sad, boys. You had to do it. There's nothing so sad as a good crimefighter turned bad.
Aunt Harriet Cooper: Batman and Robin dead? What in the world is going to become of us?
Alfred Pennyworth: Perhaps that's a better question than you realize, madam.
Aunt Harriet Cooper: Oh I wish Bruce and Dick were here. Maybe they could console me.
Alfred Pennyworth: I doubt that very much, Mrs Cooper. I doubt it very much.
Chief O'Hara: It's a requisition slip for the ammo we used getting The Batman and Robin in the big gunfight. Two hundred and ninety-seven rounds, including Tommy gun and pistol. Strange, isn't it?
Chief O'Hara: Two hundred and ninety-seven rounds of blank ammunition. You know, them blanks cost more than the real ones.
Eagle-Eye: Do you see what I see, Dove?
Dove: What do you see, Eagle-Eye?
Eagle-Eye: I see ghosts on a Batcycle!
Robin: Ghosts, huh? I don't think you crooks have the right spirits.
Penguin: Back from the grave, you tricksters, eh?
Robin: Back to send you on a honeymoon cruise, Penguin. Up the river to the pen!
Batman: Gone straight, huh?
Robin: We'll straighten you out!
Chief O'Hara: Greedy bird! Have you no conscience?
Gordon: This woman loves you, Penguin. She's still willing to marry you!
Penguin: Who, me? The Penguin? Married and kept in a bathtub?
Sophia Starr: I love you, Pengy. I'd try very hard to reform you.
Penguin: Great heavenly icefloats! Take me to prison! (waddles out)
This episode retains the first appearance of a Batvehicle other than the omnipresent Batmobile.
The Emergency Remote-Control Ejector Button, first used in this episode, is activated again in "The Bookworm Turns".
This marks the debut appearance of The Batcycle, as an early prototype, constructed from a 1959 Harley Davidson with side car, rented from a Hollywood firm in the business of supplying vehicles for movie and TV productions. A more flashier Batcycle will be seen in the 1966 Batman feature film and used throughout the rest of the TV series' run.
The Penguin: Mirror, mirror, on the wall, who's the fairest fink of all?
Referencing the line spoken by the Evil Queen to her Magic Mirror in the animated 1937 Disney movie Snow White and the Seven Dwarfs. Of course, her repeated dialogue omits the word "fink."
The Penguin: Oh, frabjous day! Callooh! Callay! After the Gotham City Police appear to have slain the Dynamic Duo, the Penguin quotes from the nonsense poem "Jabberwocky" originally part of Lewis Carroll's children's novel Through The Looking-Glass which itself is a sequel to his earlier book Alice's Adventures In Wonderland.
