I have quite a large collection of YouTube Poop motivational posters that I've made over the past view months in my DeviantART gallery. What is YouTube Poop, you're asking? Allow me to explain...
According to Wikipedia, Nintendo refused a company to release an add on for the SNES, but allowed them to use a few of their characters in their games. Unfortunately, they were not given a long enough time limit to complete most of their games. This system was called the Phillips CD-i (the "i" stood for interactive), and it was notorious for spawning the worst three Zelda games and Mario game of all time.
list of CD-i games:
Link and the Faces of Evil
Zelda and the Wand of Gamelon
Zelda's Adventure
Hotel Mario
Needless to say, the CD-i failed miserably, and its meager library of games have become rare and highly valuable.
About YouTube Poop:
YouTube Poops (often simply called "poop/s" or "ytp") are simply clips from miscellaneous games (especally from Hotel Mario and the Zelda and Link series from the CD-i) and other media, even from the Super Mario World TV series, that have been slowed down, speeded up, or altered in any way for random comedic purposes.
I have created a series of motivational posters containing various internet memes regarding the YTP series. You can find them here.
