Night of the Unicorns
The so-called "Night of the Unicorns," (coined by ubermann) occurred on the morning of Monday, April 23, 2007. This was the same night and some time after the creator of YTMND, max, introduced the "YFLY" top-right corner ads for a week. For a short time, max even applied a large bottom-right corner ad: http://content.ytmnd.com/assets/images/right_corner.gif and the image at the left: http://content.ytmnd.com/assets/images/left_corner.gif
This strange night was so named for the short-lived unicorns from 'My Little Pony' in the background of the actual YTMND website, along with the song "Girlfriend" by Avril Lavigne in the background, essentially briefly making YTMND.COM an actual YTMND. Early in the morning max decided to have some fun with the front page and YTMNDongs ventrilo users suggested using the Avril Lavigne song Girlfriend in the background of every site. User:BTape quickly made and hosted a loop at the following site: http://heyheyyouyou.ytmnd.com and max soon after made the image tile and the sound play on every page, including the news posts, site profiles, front page, etc. This change lasted nearly two hours.
Max also made the profile page for the following site produce five pop-ups for anyone who clicks it: http://popupsplz.ytmnd.com/
