I don't know what to say about this one. There are many weird wikis but this one is amazing.

Some chubby chaser apparently took his lust for women who smell like crisco and despair and created an entire alternate universe about it. He doesn't just make photoshops of Fat World's denizens (picture related is Fat World Natalie Portman) but has developed intensely detailed weights and sometimes elaborate biographies for the fatties:

This just sounds like some sad fetish until you get to the goldmine of autism:

FAT WORLD, is not only a weight gain fantasy, it's also an alternate history timeline. Unlike normal alternate history timelines, FAT WORLD is basically Our World but with the vast majority of women fat. While large wholesale changes in history haven't occurred in FAT WORLD, there are minor differences with Our World besides a how much a particular woman weighs. Here are some cultural and business examples:
> The 1970 AFL-NFL merge saw the Atlanta Falcons, Minnesota Vikings, and New Orleans Saints move to the AFL instead of the Baltimore (now Indianapolis) Colts, Cleveland Browns, and Pittsburgh Steelers. Some interesting side effects of this are that the Raiders stayed in Oakland and never ventured to Los Angeles, the Cardinals stayed in St. Louis resulting in an expansion team being awarded to Phoenix in 1995 instead of Jacksonville, the Rams never left Los Angeles, and football doesn't return to Baltimore until 2002 when it's awarded an expansion franchise along with Houston.
> World Championship Wrestling does not get purchased by the World Wrestling Federation, now WWE, instead was purchased by a billionaire who made his fortune in the Dot.com bubble. The same billionaire also purchased Exteme Championship Wrestling and merged the two organizations. Because of this the WWF/E doesn't undergo the brand extension.
> The DeLorean Motor Company is still operating and was one of the first companies, along with Apple, to use ad time during the Super Bowl to gain attention.
That page also is the first indication of the Wiki owner's intensely possessive control over Fat World.
