MiseTings

A Magic: The Gathering humor site, originally it was Mike Bregoli (MB)'s blog, which later became a satirical/humor article site similar to The Onion, but in the past couple of years the articles have been waning, and most people visit solely for the forums.

Some entries on Urban Dictionary that stem from MiseTings include Sarnath'd, Random-Miser, and soccer mom'd.

"MiseTings even has it's own WikiPedia page dude. Check out http://en.wikipedia.org/wiki/Misetings."
