Meme maybe?

Wikipedia says "A meme (pronounced /mɛmɛ/[citation needed], /miːm/[1] or /mɛm/[citation needed]) consists of any unit of cultural information, such as a practice or idea, that gets transmitted verbally or by repeated action from one mind to another." This applies to such so-called 'viral' internet phenomona as Chocolate Rain, LOLCATS, the Star Wars Kid and about a billion other things you can think of, including 98% of the content on YouTube. Recently I came across something that I think qualifies. Or at least deserves to. Or maybe it already does and I'm just late to the party (that wouldn't be a total shock).
At the Internet Movie Database, where you can find information on every film ever made or slated to be made, there are message boards where people post information, much of which is speculation about upcoming movies that is passed off as absolute fact from people who claim to have inside info. Of course, like just about every message board on the internet, it's totally unregulated and there is no way of determining who is or is not a credible source. In other words, virtually none of them are. The people who post information regarding the casting of Quentin Tarantino's World War II Drama "Inglorious Bastards" (currently listed as "Announced") seem to have a pretty good grasp on this and are taking it to the logical and ridiculous extreme, much to the annoyance of some who have no sense of humor. You can read the whole thing here (you'll need to register; it's free) but here are some highlights (it's all copy and paste; don't blame me for typos):

"Stephen Hawkins and Conan O'Brien confirmed. This is going to be one hell of a MOVIE!!!!!"

"You sap. That Hawkins thing was just a rumour. That was never going to happen. But former President Jimmy Carter has been confirmed, as has Cheeta the 75-year-old chimp from Tarzan. I can't wait."

"My brother is Tarantino's gardener, he told me Ronald McDonald and Corey Haim are attached."

"Denzel Washington is confirmed as one of the Nazi Generals.."

"I heard somwhere that Yao Ming is playing Adolf Hitler.... "

"Don't look now sports fans but none other than John Madden will be signing on to play Eleanor Roosevelt."

"Damn! I just got off the phone with the neighbour of the barber of the hair stylist of Johnny Knoxville and he told me Quentin Tarantino is going to play Tim Roth. He allso said The Rock was gonna play both Hitler ánd Roosevelt!!"

"None other than Scott Bakula is currently in talks with Quentin to play a sandwich."

"All the members of congress will play heroic soldiers getting slaughtered on the beaches of Normandy. 5000 Google employees will be Nazi extras."

"Optimus Prime will be playing Gen. George S. Patton. I smell oscar."

"Eddie Money, Hillary Duff, Larry Bud Melmon & Luke Wilson - all CONFIRMED! "

"Word has it, that.... Ann Coulter, and Condi Rice are to play, the time traveling duo of Rosencrantz and Guildenstern. The pair are to be joined by Janet Reno, in the final bunker scene, for some hot Nazi lesbian three-way action. All this, before being mistakingly shot by; Joseph Mengele, Karl Brandt, and Eva Braun. Expertly played by, Jonathan Winters, Festus from Gunsmoke, and Shemp Howard respectively."

"And who is going to play the coveted role of a young, George Herbert Walker Bush? You guessed it, Frank Stallone."

"Dr. Phil announced this morning on "The Henry Rollins Show" that he will be playing a Native American version of Dolph Lundgren with T-Rex arms."

"Heard through the grapevine... Bruce Campbell to play a young Elvis leading the charge on the beaches of Normandy. Also, Larry the Cable Guy in talks to play Churchill, but may run into scheduling conflicts as "Witless Protection 2" is scheduled to shoot concurrently."

"OSCAR BUZZ!!!! Heard this might be the breakout role that Jimmy Fallon has been waiting for! Jimmy plays a man in the wheelchair that is only able to move his right foot. Comedy ensues, but you also feel for the guy. I can't wait!!!"

"Louis Gosset Jr, Bruce Willis, Gary Glitter, Tom from Myspace, David Duke and the Quaker Oats guy confirmed."

"You heard it here first gang, Corey Feldman and Corey Haim have been spotted having lunch with QT, word round the campfire is the two corey's will be playing Ben Affleck during the rousing Pearl Harbor scene."

"The starting defensive line for the 1976 chicago bears have all signed on to play FDR's legs."

"Hold on to your hats, sports fans. It has just been reported that Frank Caliendo's impression of Charles Barkley has been inked to play a Sherman tank."

"Shamu the killer whale's clone is currently in talks to make an appearance as Mussolini. Michael Bay recently announced that he will be directing the Transformers segment of the movie, featuring Optimus Prime as a Luftwaffe B-109 suicide plane and Shia Lebouf as a wisecracking Japanese school girl. "

"Just in: IMDB.COM confirmed. The website itself is going to be in this movie."

"All you guys are the dumbest mother ****ers ever. quentin literally CALLED me and told me that the role of Adolf Hitler was taken by Jessica Simpson"

"This is actually 100% true and confirmed from a highly reliable source: Morris Day and Jerome Benton have been cast. It's not been determined what parts they will play but they will perform "Jungle Love" and "The Bird" as they are legally required to do every time they appear in public together. They will also be barefoot."
