Cisco's greatest hire? You might have hired an intern or two for the summer, but it seems that only Cisco is lucky enough to employ the (self-proclaimed) "world's most interesting intern." Greg Justice, a 21-year-old Stanford student and intern in Cisco's communications department, has posted a video of himself rapping in an effort to "harness social media to amplify Cisco's awesomeness," he tells Mashable. With lyrics like "I'm courteous and affable, my name badge is retractable, you other interns laughable," it's definitely interesting. Awkward? A little--but, hey, at least it's better than this intern. And if you haven't already, check out Inc.'s guide on managing interns.

Longevity tips from a 200-year-old company. Back in 2008 we told you the story of Crane & Co., a family-owned paper-making company that has been providing the U.S. Treasury with their currency paper for over 130 years. Despite being the sole maker of U.S. currency paper, the Boston-area company is not one to rest on its laurels. As the Boston Globe reports, Crane & Co. has been hard at work creating some incredibly high-tech security measures that will be incorporated into the Treasury's soon-to-be-released $100 bills to help protect against counterfeiting. By September, the company will produce enough paper for 2.4 billion revamped $100 notes. As CEO Charles Kittredge explained to us in 2008, "In order to remain in business for over 200 years, we've had to continually change."

Google sets its eyes on Facebook...again. With it becoming increasingly clear that Google Buzz has, to date, been a lackluster social networking tool, Google is rumored to be building a full-out social network to challenge Facebook, TechCrunch reports. The tech blog cites online comments from former Facebook CTO Adam D'Angelo in which he says that "There are a large number of people working on [the project]" and that Google "realized Buzz wasn't enough and that they need to build out a full, first-class social network."

An X Prize for the oil spill. The X Prize foundation, which used a $10 million cash prize to spur entrepreneurs to create a rocket capable of making reliable suborbital flights (read about the winner, Burt Rutan), announced a new prize yesterday. The foundation will award $3 million for an effective cleanup solution for the oil spill in the Gulf of Mexico. CNN has the news (via TechCrunch), but the details are still sketchy. According to the article, there have been some 35,000 solutions already proposed to various organizations. The challenge will be sorting through them quickly enough to actually use the good ones.

Could Apple face a class action lawsuit over the iPhone? The California law firm of Kershaw, Cutter & Ratinoff is no stranger to suing big names in the tech world. The firm previously took Facebook to court--in the form of a federal class action lawsuit--over scammy ads and offers in games like Mafia Wars and Farmville. Now, Valleywag reports, KCR is on the hunt for consumers who "recently purchased the new iPhone and have experienced poor reception quality, dropped calls and weak signals." As we've told you, the fourth iteration of the iPhone loses some reception bars depending on the way it's held. Other phones have had issues with how grip affects reception, but nowhere near the intensity this current public outcry. "So when Steve Jobs personally suggests user to 'avoid holding it in that way,'" says Valleywag, "he's handing the likes of KCR some valuable legal ammunition."

The secret to the PayPal Mafia's success. The PayPal Mafia, the founders and early employees of PayPal who went on to found start-ups such as, Tesla Motors, and LinkedIn, got their start in the electronic payment company's "scrappy" culture. On his blog, Vincent Chan, co-founder of Primitus, a Hong Kong-based web apps start-up, delves into just what that means in the words of the former employees themselves (via Techememe). In addition to enforcing an anti-meeting culture and a knack for spotting talent at a young age, PayPal founder Peter Thiel required that everyone be tasked with exactly one priority and refused to discuss almost anything with employees aside from their No. 1 intiative. Intense? Sure. But you can't argue with the results.
