Portal of Evil is a good link dump for weirdness on the internet. Here I've discovered Furries, The Hollow Earth Theory and a fetish where clothed women get their cars stuck in mud. You'll also find links to crazy religious sites, conspiracy theorists and the gloriously insane.
It's also just good for a harmless laugh. Today they link to Sugar Bush Squirrel: The World's Most Photographed Squirrel. The squirrel seems pretty content in little costumes, and it's as cute as it is mind-numbingly strange. The person in charge is running an entire industry based on her pet squirrel. In an ironic note, she lives in Boca Raton, which means "mouth of the rat".
