All your memes are belong to us

Memes didn’t begin with the Web, but you’d be forgiven for thinking so. The evolutionary biologist Richard Dawkins coined the term in his 1976 book, “The Selfish Gene,” to describe something that already existed. A meme, from the Greek “mimeme” (to imitate) was “a unit of cultural transmission, or a unit of imitation.” This encompassed phenomena from Martin Luther’s “95 Theses” to the famous graffiti drawing “Kilroy Was Here,” which dates to the beginning of World War II.
But the Web has proved to be the most fertile ground, and the site Know Your Meme has confirmed more than 2,600 of them. Below, 25 definitive memes from the Web’s first 25 years.
 Dancing Baby
1996: Considered the granddaddy of Internet memes, the baby shuffling to Blue Swede’s “Hooked on a Feeling” filled inboxes and prime-time airwaves, appearing in several episodes of “Ally McBeal.” The file was originally included with early 3D software. LucasFilm developers modified it before it was widely shared, and it was finally compressed into one of the first GIFs.
 Hampster Dance
1998: Proving that GIFs were meant for stardom, a Canadian art student made a webpage with 392 hamster GIFs as a tribute to her pet rodent. The infectious soundtrack was a sped-up, looped version of “Whistle Stop” by Roger Miller.
 Peanut Butter Jelly Time
2001: A Flash animation featuring an 8-bit dancing banana, “Peanut Butter Jelly Time” became an Internet phenomenon in the early 2000s. The catchy song was written and performed by the Buckwheat Boyz, a rap group.
 All Your Base Are Belong to Us
2001: A meme that would echo across the gaming community for years to come, “All your base are belong to us” originated in a cut scene in the Japanese video game “Zero Wing.” The poorly translated quote has persisted as an Internet catchphrase.
 Star Wars Kid
2002: Arguably the first victim of large-scale cyberbullying, Ghyslain Raza unwillingly became a meme based on a video of him swinging a golf ball retriever as a weapon, reminiscent of Darth Maul in “Star Wars: The Phantom Menace.” It was an early sign that Internet privacy was not guaranteed for anyone.
2003: Before they became spokesthings for Quiznos, two singing Spongmonkeys catapulted to viral stardom after being featured in a newsletter for b3ta, an early link- and image-sharing site. Their opening line: “We like the moon.”
 Numa Numa
2004: The eyebrow lift. The arm pumping when the beat drops. The song (by Moldovan boy band O-Zone). Gary Brolsma, sitting at his desk, showed us all what it means to “dance like no one’s watching.”
 O RLY
2005: Originating on the community site 4chan, the wide-eyed owl was used to show sarcasm, becoming a precursor to other reaction memes.
 Chuck Norris Facts
2005: Chuck Norris was the Internet’s first “most interesting man in the world,” crowned the avatar for mythical men with impossible strength, attitude and swagger. “There is no theory of evolution,” as one “fact” says. “Just a list of creatures Chuck Norris allows to live.”
 I Can Has Cheezburger?
2007: Animal-based memes are a dime a dozen, but the “I Can Has Cheezburger” blog, whose mascot is a surprised, hungry British shorthair cat, brought them into the mainstream. The blog was created by Eric Nakagawa and Kari Unebasami.
2007: Before there was clickbait, there was the Rickroll. Popularized on 4chan, the gag — springing a Rick Astley video on an unsuspecting victim — has appeared during a session of the Oregon legislature and even on the White House’s Twitter feed.
 Success Kid
2007: Based on a photo that Sammy Griner’s mother, Laney, posted to Flickr when he was 11 months old, the meme describes something that goes better than expected. In 2015, Sammy’s fame helped his family raise more than $100,000 to offset the costs of a kidney transplant for his father, Justin.
 Dramatic Chipmunk
2007: A simple, five-second video clip of a chipmunk — ahem, actually a prairie dog — suddenly turning its head, from the Japanese TV show “Hello Morning.” The maneuver is set to an exaggerated bit of music from 1974’s “Young Frankenstein.”
2008: This portmanteau meme was an early example of an “advice animal,” depicting the vicious dinosaur deep in introspection, and pondering wordplay and life’s general paradoxes.
 Deal With It
2010: In this GIF, sunglasses slide onto a smug canine’s face. It was around as an emoticon on the SomethingAwful forums for a while, then became a meme when the site Dump.fm held a contest encouraging users to create their own versions, with sunglasses sliding onto various faces and objects.
 Hide Your Kids, Hide Your Wife
2010: “So y’all need to hide your kids, hide your wife and hide your husband ’cause they’re raping everybody out here,” Antoine Dodson emphatically told a TV reporter after an intruder attempted to assault his sister. The clip spread quickly on YouTube, leading to Auto-Tuned versions and remixes.
 Nyan Cat
2011: The combination of an animated 8-bit cat (originally dubbed “Pop-Tart Cat”) with the insanely catchy tune “Nyanyanyanyanyanyanya!” blew up on YouTube, becoming the site’s fifth-most-viewed video of 2011 and inspiring fan illustrations, designs and games.
2012: Originally uploaded as “Gersberms . . . mah fravrit berks” and later “BERKS!,” the text superimposed on this meme mimics the garbled speech of a person with a retainer.
 Bad Luck Brian
2012: Takes goofy yearbook photo. Gets face plastered all over the Internet. His real name is Kyle Craven, and he’s Internet famous thanks to his friend Ian Davies, who uploaded the photo to Reddit with the text “Takes driving test . . . gets first DUI.”
 Grumpy Cat
2012: The original photo of Tardar Sauce (that’s her name) racked up 1 million views on Imgur in its first two days. The meme has since spawned books, a comic book, an endorsement deal with Friskies cat food and a made-for-TV Christmas movie, “Grumpy Cat’s Worst Christmas Ever,” with Aubrey Plaza voicing Grumpy Cat.
 Ridiculously Photogenic Guy
2012: Uploaded to Reddit on April 3, the photo of the handsome runner quickly garnered 40,000 upvotes. Derivatives include Ridiculously Photogenic Metalhead, Ridiculously Photogenic Syrian Rebel, Ridiculously Photogenic Prisoner and Ridiculously Photogenic Running Back.
2013: In February 2010, a kindergarten teacher in Japan uploaded pictures of Kabosu, her adopted shiba inu, to her personal blog, and a meme was born. It usually features broken English phrases in the comic sans font, representing an inner monologue.
 Crying Michael Jordan
2014: The basketball great got a little emotional during his 2009 Hall of Fame induction speech. Around 2014, meme-makers started using an Associated Press photo, superimposing Jordan’s face over failures of all sorts.
 Ice Bucket Challenge
2014: While the origins of this one are unclear — people have been doing cold-water challenges for years — the results weren’t. The ALS Association raised more than $100 million in a month, compared with $2.8 million over the same period the previous year.
 Left Shark
2015: During the Super Bowl XLIX halftime show, Katy Perry performed with two dancing sharks. One shark stuck to the routine. The other, well, did his own thing — and became an Internet sensation.
