You're the Man Now Dog is a popular humor site.The creator, Max Goldberg, made the first site after watching the trailer to Finding Forrester. This first site (recreated here) consisted of some ASCII art and Sean Connery's "You're the man now, dog!" line from the trailer. As other people started to create their own Spinoffs of the page by copying the code, Max started listing them. Eventually the list became overly long, so Max bought an entire domain for the sites and made an easy-to-use site generator. And the rest is history.The main feature of the site is to allow users to create their own pages, or YTMNDs, using a GIF animation, an MP3 file and the site's patented zooming text.It has its own wiki.
After the trailer that started it all was posted as an YTMND, many users started wondering what would have happened if Max had decided to use one of Sean Connery's other lines, namely "Punch the keys, for God's sake!" or "Yes...Yes!". Eventually, some users started creating Bizarro Universe versions of popular YTMND fads under the label of PTKFGS. Soon after, sites with the YESYES label followed, which is basically a Take a Third Option spin on the fads. Then, since Connery only had these three lines in the trailer, many users worked around it by using some of his other lines from the film to create a fourth Alternate Universe. Which one of the many candidates is the true fourth universe is still under dispute, but the general consensus seems to be that the fourth universe is in fact a Multiverse known collectively as "Fourth Corner".
HEH is considered by some to be the official 4th Corner Universe, as it is also in the trailer. However, those against this idea point out that HEH is technically a part of the "Yes...Yes!" line.
Let's not forget YTMNSFW, the Not Safe for Work version suitable for more mature stuff.
Cloud Cuckoo Lander: Vinny Weapons, the user who always made the same comment: "the robots have taken me. please send help." Also, the behavior of trolls Pilleater and Johnny Lurg often reaches this territory, such as the time the former user pretended that he went blind. Two months later, he posted, "I can see again!" The user zomglolwtfzor usually epitomizes this trope, but occasionally breaks character.
Giant Enemy Crab: YTMND was one of the first sites to popularize the phrase, and it has become somewhat of an accepted fact that in the YTMND universe, Samurai actually did battle Giant Enemy Crabs in Ancient Japan
Greedy Jew: Many users poke fun at the site's owner, Max Goldberg, with this stereotype. He usually takes it in stride.
Often an anime site will be immediately downvoted, and a comment will be posted linking here
Same goes to MMORPG stuff. This was because, in the early days of YTMND, many World of Warcraft related YTMNDs were created and linked to the World of Warcraft forums, generating massive numbers of views every day, which annoyed the general YTMND population, having to see sites containing inside jokes about a game most of them didn't play on the front page day after day. This still happens occasionally, and because of this, World of Warcraft - related sites are usually downvoted upon creation.
Jail Bait Wait: Many users eagerly counted down the days until Julianna Rose-Mauriello, the actress who played Stephanie on LazyTown, would become 18, and made many YTMNDs celebrating the occasion when it actually did happen
Killer Rabbit: Happycat/The NEDM cat, who often burns humans alive as retaliation for humans burning cats
Laughably Evil: This seems to be the entire appeal of the Moon Man fad/character
The user Umfuld, who thinks only the kinds of sites he makes are any good and anyone who makes different kinds of sites is deliberately trolling and trying to ruin YTMND, and he does things like automatically downvoting the sites of every user he doesn't like using multiple alternate accounts because of this
This was also the reasoning of the famed user "inkdrinker", who believed that the only YTMND's that were any good followed the original site's mission of "picture, text, sound". He downvoted thousands of pages that included videos, effects, soundclips that went on longer than a few seconds or anything that bucked the trend of the original sites.
