The "Stolen Pace-Egg" Case

In the late 1890s, a frantic man actually sent a letter to 221B Baker Street (which didn't exist as a real address at the time, so the post office forwarded it to Conan Doyle). The man begged Sherlock Holmes to investigate the "theft of a valuable pace-egg" (a traditional dyed Easter egg) from his kitchen. Conan Doyle was so amused and bewildered by the insignificance of the "crime" that he framed the letter and hung it in his study.

Holmes’s Terrible Roommate Habits

While modern adaptations make Holmes look cool and eccentric, book fans online like to compile lists of why he would be an absolute nightmare to live with. According to Watson's journals, Holmes: Kept his cigars inside the coal scuttle, pinned his unanswered letters to the mantelpiece using a massive dagger, kept raw, infected bloodstains on the dining table for "chemical testing", and would randomly wake up at 3:00 AM to play the violin loudly while staring at the ceiling.

The Real Reason Behind "The Hound of the Baskervilles"

When Conan Doyle finally agreed to write a new Holmes story after killing him off, he didn't actually want to bring him back to life yet. The Hound of the Baskervilles is famously set before Holmes's death. The funny part is how the book came to be: Conan Doyle was on a golfing holiday with a friend who told him a creepy local ghost story about a phantom hound. Conan Doyle realized he could make a fortune if he just slapped Sherlock Holmes into the plot, admitting to his mother in a letter that the book was a calculated cash-grab to fund his true passion—buying a new automobile.

Dr. Watson's "Migrating Wound"

A massive running joke in the Sherlockian community centers around Dr. Watson’s war injury. In the very first book, A Study in Scarlet, Conan Doyle writes that Watson was shot in the shoulder by a Jezail bullet. However, in the second book, The Sign of Four, Conan Doyle completely forgot what he wrote and stated that the bullet wound was in Watson's leg, causing him to walk with a limp. Fans lovingly joke that Watson was shot with a magical, migrating bullet that traveled through his body over the course of a year.

The Real-Life "Disguise" Disaster

Sir Arthur Conan Doyle based Sherlock Holmes on his university professor, Dr. Joseph Bell, who possessed incredible powers of observation. Attempting to be a detective himself, Conan Doyle once wore a disguise to investigate a real-world crime scene. However, his disguise was so poorly put together that a local street urchin immediately recognized him, yelled his name, and a crowd gathered to mock him. He never tried undercover detective work again.

Memeing the "Sherlock Cliffhanger" Traumas

Long-time internet communities on platforms like Pinterest and Cheezburger continue to generate nostalgia memes about the "Great Hiatus"—the agonizing two-year wait between seasons 2 and 3 of BBC’s Sherlock. The era spawned absurd, viral fan theories that are still laughed about today.

The Brain Attic vs. TikTok

Podcast and cognitive-science discussions are currently using The Deductionist Podcast's "Sherlock Holmes vs The Internet" episode as a springboard to debate modern memory. Holmes famously believed the human brain was like a small "mental attic" that should only be filled with useful data, discarding things like the solar system. Users are jokingly debating whether scrolling through social media has permanently ruined their own "brain attics".

The Ghostly Rejection

Fans online frequently mock the irony of Conan Doyle's life. He grew so deeply resentful of Sherlock Holmes eclipsing his "serious" historical fiction that he killed him off. When public outrage forced him to bring Holmes back, he famously charged extortionate prices hoping publishers would refuse. They paid it immediately. Furthermore, while Holmes was a strict rationalist, Conan Doyle famously believed in spiritualism and fairies, prompting fans to joke that Holmes would have absolutely hated his own creator.

The "All is Discovered" Prank:

Shooting the Wall Out of Boredom

A favorite scene among meme creators occurs in The Adventure of the Musgrave Ritual, where a deeply bored Holmes sits in his armchair and shoots a patriotic "V.R." (Victoria Regina) into his brick wall using a pistol and a box of amateur chemical experiment supplies.

The Ridiculous "Unrecorded Cases"

Literary fans on Reddit and TikTok regularly laugh over the fictional "throwaway cases" Conan Doyle referenced but never wrote. The internet's favorite is the Case of the Politician, the Lighthouse, and the Trained Cormorant, closely followed by a mystery solved strictly by "the depth to which the parsley had sunk into the butter on a hot day."

The "Norbury" Safeword

One of the most popular book anecdotes shared online comes from The Adventure of the Yellow Face. In this story, Holmes completely miscalculates, gets the entire theory wrong, and the mystery resolves itself without him. Humiliated, Holmes tells Watson: "If it should ever strike you that I am getting a little overconfident... kindly whisper 'Norbury' in my ear." Fans love bringing this up to prove that Holmes wasn't a perfect, unfeeling machine.
