It's first thing in the morning and you're at the office. You're sipping your coffee and sifting through e-mail, but you're not quite ready to delve into the real work of the day. So what are you gonna do? Fire up your Web browser and distract yourself by wasting time on the Internet.

Ah, but where to start? In the name of science, we culled through hundreds of bookmarks to determine the best sites for spitting in the face of productivity.

But first, some ground rules: We're including only browser-accessible destinations (so no World of Warcraft or Google Earth), and for the most part, we shied away from anything overly obvious or highly specialized: No straight news, fantasy sports, Web mail, shopping, matchmaking sites, stock quotes, or discussion forums for your 1982 Camaro. We also tried (though this was tricky) to recommend sites that might be conceivably accessible from work: No adult content, poker, or games that can't easily be closed when the boss strolls by.

Consider yourself amply warned: Don't read this story if you plan on getting anything done for a while.
