!!Tropes:

* AdaptationDistillation: Dennis does not own Ruff the dog in the television version, while George Wilson acquires a terrier named Fremont.
* AnimatedCreditsOpening: Featuring Dennis as an abstract tornado, knocking over paint cans and literally shaking the neighborhood houses.
* AsHimself: Spring Byington and Sandy Koufax
* BaseballEpisode: With Special Guest Star Sandy Koufax AsHimself.
* BillingDisplacement: For the first three years, the credits featured Jay North by himself, and then one screen with three credits in the order of Herbert Anderson (Henry), Gloria Henry (Alice), and Joseph Kerns (Mr Wilson). When Gale Gordon joined the cast, he became the second person to be credited, followed by Anderson and Henry.
* CatchPhrase: For Dennis: "Heyyyyyy, Misssssster Willllllllllllson!", "Good ol' Mr Wilson", "Jeepers!", and "I was only trying to help!". For Mr. Wilson: "Oh, Great Scott!"
** Lampshaded at the end of one episode:
--> '''Mr Wilson''': I'm sorry, Alice, I was only trying to help.
--> '''Dennis''': Jeepers, Mr Wilson! You sound just like me!"
--> '''Mr Wilson''': I do?!?! Jeepers!
--> '''Dennis''': Great Scott!
* CoolOldGuy: George Wilson, in Dennis's eyes at least.
* CrankyNeighbor: George Wilson, in everyone else's eyes.
* CrossOver: Jay North made a guest appearence in an episode of ''TheDonnaReedShow'' as Dennis. Apparently the Mitchells and the Stones live in the same neighborhood.
** Spring Byington appears in one episode as herself visiting her niece, the mother of one of Dennis's friends. Although playing herself, Dennis refers to her by the name of her character from ''DecemberBride''. (Which is somewhat ironic, as Jay North would grow up to resent the fact that everyone thought of him as Dennis, making it next to impossible to find post ''Dennis'' acting work.)
* DemotedToExtra: Joey was Dennis' best friend in the comics, but he was pushed to the background.
* FreeRangeChildren
* GenreSavvy: George Wilson. In one episode Wilson and the Mitchells decide how to approach Dennis to solve that week's problem. After they reach a solution Alice asks Wilson what he's thinking about and George says he's just trying to figure out how this solution will eventually backfire.
* IneptAptitudeTest: Dennis takes a standardized IQ test in school which reveals him to be a genius; but it turns out a wad of gum he left on the underside of the paper screwed up the scoring.
* [[JustEatGilligan Just Eat Dennis]]
* LimitedWardrobe: Jay North always wore a striped shirt and overalls like comic strip Dennis for the first three seasons. For the fourth he was allowed to wear regular pants, but they were the same color as the overalls and he still wore the striped shirts.
* LuckyRabbitsFoot: An episode called "The Lucky Rabbit's Foot". In it, Dennis has what he thinks is a lucky rabbit's foot. With recent bad luck Mr. Wilson has been having, Dennis offers to let him borrow the foot. Mr. Wilson, however, doesn't believe in such superstition and doesn't take the foot. Immediately thereafter, his bad luck continues when something jams his lawnmower, and he runs over his garden hose with the mower.
* MaintainTheLie: In one episode John Wilson fears a glamourous movie star will feel he is too old to write her life story, so he inlists Henry Mitchell to meet with her as him instead. Cue the hilarity when both Alice and Eloise come home early.
* MenaceDecay: Like the comic strip, the first few episodes had Dennis being more of an actual menace then the innocent naive boy "just trying to help" that later episodes turned him into.
* NotAllowedToGrowUp
* NotNowKiddo
* ParentExMachina
* PutOnABus: Mr. and Mrs. Wilson, after Joseph Kearns died suddenly in 1962, during the third season. As production of new episodes for the 1961-1962 season was still ongoing, the following changes took place over the next several months, continuing into the fall 1962 season:
** '''Initially''': Two scripts where Mr. Wilson was either non-essential to the story or did not appear were shot first, with his lines either being removed or rewritten for other characters.
** '''The last six (6) episodes of Season 3''': Gale Gordon is introduced as George's brother, John. George is away on business, settling an estate "out east." The bus at this point is warming up.
** '''Starting with Season 4''': George and Martha move from town, presumably "out east." (At this point, Sylvia Field, who played Mrs. Wilson, was let go.) With the bus now departed, there are only a few scattered "blink-and-you'll-miss-them" mentions of the Wilsons in the first few episodes of the new season, after which they [[ChuckCunninghamSyndrome are never referred to again]].
* RoadSignReversal: Dennis mistakenly believes the street sign at the corner is reversed, so he turns it, whereupon a swimming pool company goes to the wrong house and basically destroys Mr. Wilson's backyard.
* SuspiciouslySimilarSubstitute: Gale Gordon replaced Joseph Kearns as George Wilson's brother John for the final season after Kerns passed away. Oddly enough, Gordon resembles the newspaper image of George Wilson much more than Kerns did.
** Although to be fair, John wasn't completly a clone of George. Being slightly younger he was still working and not the cranky retiree that George was. John seemed to accept Dennis more as an equal, and even conspired with him in a few episodes. The characterizations of Martha and Eloise Wilson on the other hand were indistiguishable.
** The two episodes filmed between Kern's last episode and Gordon's first were obviously rewritten with two [[SuspiciouslySimilarSubstitute SSSs]]: Grocer Mr Quigley [[BaseballEpisode coaches Dennis's Little League Team]], and Uncle Ned - who previously was a health nut who drove George crazy with excersise and fitness - now is in such bad health that he suddenly gets exhaused as he prepares his flower garden for a neighborhood contest.
* ThirdPersonPerson: Opie the Fix-it Man in "Dennis and the TV Set".
* UmpteenthCustomer: An episode revolves around Mr. Wilson trying to be this to win a shopping spree.
