Do you ever find yourself wondering what ever happened to Chris "Leave Britney Alone!" Crocker or the adorable Numa Numa guy? If you're mildly curious, head over to PC World who put together a list of the most outrageous Web celebrities and their fate after their 15 minutes were up.

Here are some highlights:

Chris Crocker: After his unforgettable emotional video plea became an overnight sensation, Chris Crocker went on to become a paparazzi favorite, a talk-show guest, and now a music artist with a song on iTunes. His new single, called "Mind in the Gutter," is getting plenty of radio play apparently, and in this video, he thanks fans for taking him all the way to number #42, and then scolds the illegal downloaders for not paying the 99 cents. Can you blame them?

"One Red Paper Clip" guy: After trading a single red paperclip (and a few other things) for a two-story farmhouse back in 2005, Kyle MacDonald stepped into the spotlight and even earned a mention in the "Guinness Book of World Records." Today Kyle is promoting a new book detailing his One Red Paperclip adventure and is looking to trade his two-story farmhouse for "several 1990 Burgundy Dodge Caravana with low miles." Any takers?

The Back Dorm Boys: You probably never knew their names, but who could forget Wei Wei and Huang Yi Xin lip synching to the Backstreet Boys? This talented duo graduated from college in 2006 and landed corporate deals with Motorola, China's Sina.com Internet portal, Pepsi, and Taihe Rye, a Beijing media company that helped them become full-fledge TV stars in China. Not bad for a couple of kids that started out lip-synching boy band songs.
