There is probably someone, maybe several people, who drive you absolutely bonkers at work. Gossips, liars, know-it-alls. Every office has them.

So how do you deal with the worst of the worst at work? Marc Hershon, co-author of "I Hate People," spoke to Carol Costello on CNN’s “American Morning” Friday.

Carol Costello: We were intrigued by your title, "I Hate People." Why did you title it this way?

Marc Hershon: Well, for me, it's become a bit of a personal mantra. I've heard a lot of people mutter it under their breath professionally, in retail and business. It's not really the people we hate so much as it is their behavior. But there's something sort of viscerally satisfying to be able to say, “I hate people” when they drive you crazy.

Former Illinois governor Rod Blagojevich has stepped back into the spotlight, if only for a few minutes.

Over the weekend he surprised the audience at a comedy show in Chicago that pokes fun at almost every aspect of his life – from his wife – to his political career.

Blagojevich made a special appearance Saturday night at Second City's production of "Rod Blagojevich Superstar."

As the curtain rose, there was Blagojevich with his arms stretched out mimicking a crucifixion.

The play is a parody of "Jesus Christ Superstar" and lampoons his rise and fall in politics. He opened the production with a monologue.

"What they say to you before you go out on stage I thought is very interesting and that is ‘we got your back.’ I've been in politics and that's not anything anybody said to me."

As Blogojevich left the stage, the cast launched into a song that asked, "What kind of idiot sells a Senate seat?" Of course, Blagojevich was indicted on charges he tried to sell President Obama's old Senate seat.

The former governor stuck around after the show to participate in some improv where he took issue with one particular part of the show, saying "That brush he has, it’s too small.”

The reviews were mixed. Some audience members cheered throughout the show while others found it a bit awkward. "He laughed a few times, he was quiet a few times, it was queasily uncomfortable even sitting behind him a few times."

The play was supposed to have its final performance this month but due to its popularity Second City has decided to extend it until August. Meanwhile, Blagojevich is facing as much as twenty years in prison if convicted on some nineteen counts, including racketeering and extortion.

Mike Doyle is dying to make a living. Literally. He has made a name for himself as the actor who “dies” all the time onscreen. But what is it like to get killed so often? We met the very “alive” actor and he told us how he actually gained his trademark status. “The first time out, I thought, oh interesting, it would be fun to die,” he said. “And now when I turn the page, I’m like, ‘Oh, man. Again? Again?'”

And what is his technique to making the scenes so believable? "It’s not as easy as you think," he says. In one of his death scenes he kept his eyes closed and they started to flicker, so he figured next time – play a dead man with his eyes open.

Fortunately for moviegoers who want to see him staying alive, his next role is with Nicole Kidman in the upcoming movie, "The Rabbit Hole." He won’t have to rehearse playing dead for that one, but who knows now that casting agents get to see him play out his last goodbyes so well in our CNN "American Morning" piece.

Coldplay's “Viva La Vida” is more than just their biggest hit – it's a phenomenon – selling a whopping 6.8 million copies, according to the International Federation of the Phonographic Industry. Guitarist Joe Satriani has filed a lawsuit claiming copyright infringement, saying the mega-band copied his song “If I Could Fly,” from 2004, to create their mega-hit. In court documents, Coldplay has denied those allegations.

Satriani, famous himself in the world of rock – now plays in the band, Chickenfoot, with Sammy Hagar. Hagar lays on the sarcasm in support of Satriani. “I was shocked to that Joe would steal that song from those guys,” Hagar said. “Joe you just took and erased the singing and the lyrics and made an instrumental out of it.” “And somehow, I did it four years earlier,” Satriani quipped.

The case has captured the imagination of YouTubers all over the world – most of whom are more than eager to prove Satriani right. One posting, a note-by-note analysis, by a Canadian guitar teacher has gotten nearly 700,000 hits. Then there are the “mash-ups,” where YouTubers put Coldplay's lyrics over Joe Satriani's guitar riff. Some of this stuff is so cleverly done it's gotten the attention of Satriani's attorney.

“What is fascinating about YouTube is you get 1,000 good ideas as a lawyer you could adopt and use in court,” attorney Howard King says.

But, musicologists, like Prince Charles Alexander, who's produced records for Mary J. Blige and Usher, say mash-ups can be deceiving. “You don’t pick up the guitar and invent music. You actually are inspired by someone else that played,” says Alexander, who teaches at the Berklee College of Music in Boston. “So you as an outsider who are mashing these two records up and saying "Wow look how similar they are," are actually looking at a process that's been going on for a very long time.” Alexander says you can mash-up many well known and make them sound the same.

Coldplay’s lawyer told us the band can’t comment on pending litigation. However, Coldplay front man Chris Martin wrote on the band's website, it was, "initially a bit depressing" but now it’s “inspiring." And he adds: “Now we've got more to prove than ever before.”
