  • Sharon Osbourne Bashes NBC

    The Event: When Sharon Osbourne announced her "America's Got Talent" departure in July, she declined to comment on why she was leaving. But on Monday, <a href="" target="_hplink">she claimed it was because NBC had fired her son Jack</a> from the show "Stars Earn Strips" after he was diagnosed with multiple sclerosis. "I just can't be fake," she explained. "It's discrimination, and it was badly handled." The Lesson: Blood runs thicker than water.

  • Lena Dunham And Jon Hamm Introduce The "New Yorker" iPhone App

    The Event: <a href="" target="_hplink">Lena Dunham put together a clever video featuring herself and "Mad Men" star Jon Hamm to introduce The New Yorker iPhone app</a>. Thanks to a few technology jokes from the small-screen duo, the video was all over the web instantly. Long live Hannah Horvath and Don Draper! The Lesson: If you want publicity, leave it to two of the biggest geniuses in the TV industry.

  • A Chinese Sitcom Supposedly Rips Of "Friends"

    The Event: The hit Chinese sitcom "Ipartment" was accused of basing its plot off of "Friends" and lifting jokes directly from "How I Met Your Mother" and "The Big Bang Theory." "We didn't copy the American sitcom," <a href="" target="_hplink">a show rep said when confronted about the issue</a>. "Comedies have stereotypes, like the handsome man, the gorgeous woman, the cheap man and so on. They have that in many comedies. Our creation is not plagiarism, but more a homage to the American sitcom." The Lesson: Being a continent away doesn't keep you safe from the plagiarism police.

  • Keri Russell's TV Show Gets Picked Up

    The Event: Despite her recent flop in the short-lived "Running Wilde," "Felicity" star <a href="" target="_hplink">Keri Russell is headed back to the small screen for FX's "The Americans,"</a> which was picked up for 13 episodes this week. Russell will play a KGB spy living amongst American citizens in Washington, D.C. Felicity gets another chance! The Lesson: When people love something (or someone), they have a hard time setting it free.

  • "Arrested Development" Starts Filming

    The Event: Despite the tweets and confirmations that a fourth season of "Arrested Development" was indeed happening, diehard fans of the series were afraid to believe it. But on Wednesday, <a href="" target="_hplink">photos from the set hit the web</a>. It's happening! The Lesson: Sometimes it isn't too good to be true.

  • The "Idol" Rumors Continue

    The Event: We had another week of inconclusive "American Idol" rumors. <a href="" target="_hplink">Alanis Morissette</a>, <a href="" target="_hplink">Sean "Diddy" Combs</a>, <a href="" target="_hplink">Nick Jonas and Pharrell Williams</a> are all supposedly in talks to join the judges panel. Can't these guys make a decision already? The Lesson: The waiting game can only last so long.

  • "90210" Stars Get Back Together Again

    The Event: Old Navy has a way of bringing together '90s stars. First, it was <a href="" target="_hplink">Mayim Bialik and Joey Lawrence of "Blossom" fame</a>. But now, <a href="" target="_hplink">"90210" fans are rejoicing over commercials starring Jennie Garth, Luke Perry and Jason Priestley</a>, who were in a love triangle on the series. The Lesson: It's never too late to rekindle an old flame ... or two.

  • "Here Comes Honey Boo Boo" Premieres

    The Event: Alana "Honey Boo Boo" Thompson taught us a lot this week about her family with the premiere of her "Toddlers and Tiaras" spinoff. The Thompsons went to auctions, <a href="" target="_hplink">participated in red neck games </a>and taught us some new words, including "redneckonize." When her family tagged along for her 17-year-old sister Chickadee's prenatal check-up, <a href="" target="_hplink">we learned a new name for female genitalia -- biscuits, which you can find out the original of here</a>. The Lesson: There are always ways around censorship.
