Kitty: What is wrong with you?! Were you dropped on your head?!A explanation for a character's eccentricity, ditziness, lack of intelligence, brashness, etc. is for them (or others) to harm their head as a infant or a child. A possible cause of this trope could be that they were accidentally dropped by their Alcoholic Parent, who had a little too much to drink. In some cases, they were actually pretty intelligent before the incident happened. One variation of this trope is that the character's mental deficiencies are not from a head injury but by them ingesting something harmful and toxic such as paint chips or alcohol. Another is that the brain damage was due to the character being deprived of something that's essential or substantial to having a relatively healthy body. If this trope is Played for Laughs, a character may jokingly or cheerily suggest to the others that a daft moment that another character (who usually has no disabilities and is mostly functional otherwise) just had was due to them injuring their head in their childhood. However, if it's Played for Drama and the character genuinely had head trauma in the past, it's used as a indication that the character was abused as a child or had a very dysfunctional childhood (they may also have a head deformity because of it). Related to Easy Amnesia, Tap on the Head, Hard Head, Circling Birdies. A classic example of a Hilariously Abusive Childhood.

Anime and Manga
- In Dragon Ball Z, when Goku was a baby he was just as violent as all Saiyans are, until he accidentally hit his head and became the kind-hearted hero everyone knows and loves. It was even lampshaded by his evil older brother Raditz, who point-blank asks Goku if he did hit himself in the head as a child and Goku not only confirms it, but even adds "I still have the scars, you know".
- In Pokémon: The First Movie, this is possibly the reason Mewtwo goes insane. As a child, he was not allowed to come to terms with fellow clone Ambertwo's passing away naturally. The scientists gave him a heavy tranquilizing serum to put him back to sleep until he developed into an adult. He wakes up confused, bitter and angry with little to no memory of why.
- A variation of the trope occurs with Martin Soap from The Punisher: We see the nurse dropping him on his head just after being born, but he doesn't end up with any mental handicap for it (it's just there to show the crap life shoves on him started very early and never let up).
- Cyclops of the X-Men suffered brain damage when he was a child after being pushed out an airplane with his brother (Havok) with only one parachute. Besides amnesia, the part of his brain that would have regulated his optic blasts was damaged, causing them to be "on" all the time. The blasts are only controlled by his ruby quartz visor and his eyelids.
- Obelix in Astérix got his Super Strength from falling in a cauldron of magic potion when he was small. Although it gives him a useful power, it's played as this trope, and there's several implications that it permanently altered his personality into the sweet, childlike attitude we see - for instance, when reverted to childhood by magic, he loses his power and becomes serious, deep-thinking and quite grumpy.
- Batman villain Black Mask was dropped on his head by his parents while being born. This was just the first incident in a long line of abuse and neglect his parents inflicted on him. It's implied that the incident may have been a contributing factor in Black Mask's unstable mental state and extreme mood swings.
- In a number of Axis Powers Hetalia fanfictions, such as The Hearth Series, it's revealed that Germany can't remember his childhood as the Holy Roman Empire because of injuries. Given that the series has Holy Roman Empire going to war before his "death", it's not that big of a leap.
- This played with in the Gensokyo 20XX series with Reimu and Chen. In Reimu's case, this is a variant and a subversion in that, aside from being age-regressed, she technically isn't a child but this trope comes into play when she eats rat poison in 20XXV, the effect of which leaves her near-blind and a heavy sleeper, though her intelligence remains intact, then again, in 20XXII, she was injected with sedatives every few hours for screaming, so that may have also had an effect on her that either faded with time or wasn't so apparent until now. In Chen's case, she was brain damaged as a result of her suicide attempt by drowning during the events of 20XXIV, which left her unable to talk. This explains her speech impediments that we see during 20XXV.
- According to Kill la Kill AU, Nui fell on her head when she was a year old and, apparently, Satsuki chocks the fact that she doesn't take messages too well because of that.
- Minato in Fairly English Story suffered from brain damage in the car accident which killed his parents. However, this didn't harm his intellect or emotional maturity. Rather, it leaves him unable to naturally convey emotions without intentionally trying.
- From Train Tracks, this trope is the reason as to why Satsuki "Minjonet" Kiryuuin has epilepsy. To elaborate further, her parents were having fight and she was hit with a beer bottle.
- In the My Little Pony: Friendship Is Magic fanfic Asylum, Rainbow Dash had an accident as a foal that left her disabled. She can fly but even with physical therapy she isn't on par with most other pegasi. She received head trauma that left her with a Speech Impediment, and which might be part of the reason for her temper.
- In the Naruto fanfic Team 8 Kurenai wonders if Gai had been dropped several times on his head as an infant. She concludes more realistically that the stronger a jonin is, the more wackier they behave (and fears that she will become eccentric as well).
Films — Animated
- In Happy Feet, the fact that the penguin Mumble's egg was dropped by his father is the main reason he can't sing, and the film does everything it can to compare it to this trope without actually saying it.
Films — Live-Action
- In The Goonies, it's implied that Sloth's deformity was caused by being dropped as a baby. When Ma Fratelli tries to calm him down by singing "Rock-a-bye Baby", Sloth reacts to the line "the baby will fall" as if it has unearthed Repressed Memories, precipitating his Heel–Face Turn.
- Shadow of a Doubt: The film implies that a brain injury suffered when he was hit by a car as a child is what caused Uncle Charlie's "problem".

- In Bio-Dome, there's a scene where one of the "heroes'" mothers is holding the other's head under water to teach them how to hold their breath for long periods of time.
- A Russian folk parody of an old Soviet song says: "Our youth threw us onto campaigns with sabers, our momma dropped us head-down on ice, and if our momma didn't drop us head-down on ice, no campaign with sabers would be possible". Original Russian: "Нас бросала молодость в сабельный поход, нас роняла мамочка головой об лед, кабы не роняли нас головой об лед, то не состоялся бы сабельный поход".

- In Romance of the Three Kingdoms, Liu Shan is renowned as an inadequate successor to Liu Bei, with his childhood nickname "Adou" becoming a Chinese byword for someone utterly useless. This is probably because his father had dashed his infant son to the ground in anger that his general Zhao Yun had risked his life to rescue the kid, saying, "[b]rothers are as hands and feet; wives and children are as clothing. You may mend your torn dress, but who can reattach a lost limb?"

- At one point during Baldur's Gate II, should a male CHARNAME make the mistake of saying that he "doesn't rightly know" where to go next with Jaheira during a very bad time for her, she will accuse him of sounding like he'd been dropped on his head as a child. Or kicked.
- This is eventually revealed to be the source of Marumu's emotionless Cloud Cuckoo Lander tendencies in Heart De Roomate, the result of a fall off a small cliff some years before. Not quite Played for Drama, though, since this is revealed by her brother, who not only explains that she's been in therapy in the meantime, but also thanks Yusuke for helping her along (since their relationship escalated, she's been showing more signs of improvement).
- Cranky villagers in Animal Crossing will state that as a child Pascal was hit by a soccer ball in the head, and after that he began spouting unusual philosophy. It's unknown if that's true or just the animals being rude.
- In Fire Emblem: Binding Blade, the poison that a teenaged King Zephiel was tricked into taking as a young man is repeatedly stated to have been the catalyst that left him not quite the same. A number of similar poisons in the real world (such as mercury) can and do result in personality-warping brain damage, including paranoia, increased aggression, and decreased impulse control... just like it happened to him.
- 8-Bit Theater: Black Mage asks Fighter whether he was dropped on his head a lot as a child, to which Fighter answers, "Maybe..."
