Last night's Oscars was mostly squeaky clean but for winner Jean Dujardin's acceptance speech. The French actor, who brilliantly portrayed a fading silent movie star in, The Artist dropped the French equivalent of the F Bomb! But the actor is not the first to start trouble during the live telecast. Here are 5 other onstage moments that proved scandalous.

1. Michael Moore is Booed After Comments about President Bush

In 2003, Michael Moore won the Oscar for his rousing portrait of gun use in the United States. Bowling for Columbine not only stirred a major debate concerning gun control, it was also a massive box office success. But alas, Moore's winning streak came to an end when during his Oscar acceptance speech he went into a rant about President George W. Bush. It may be argued that the controversial filmmaker was simply ahead of his time since Bush bashing didn't become the norm until a couple of years later. He said:

We live in the time where we have fictitious election results that elects a fictitious President. We live in a time where we have a man sending us to war for fictitious reasons. Shame on you, Mr. Bush, shame on you. And any time you've got the Pope and the Dixie Chicks against you, your time is up.

Moore was booed off the stage during the speech. Later on, Chris Rock was one of the celebrities who came to his defense citing the standing ovation that Roman Polanski received, even though he could not enter the US due to rape charges, as strange compared to Moore's poor reception. Moore went on to direct Fahrenheit 9/11, a film solely about Bush's corrupt presidency. Though it became of the most successful documentaries of all time, it was not honored with any nominations.

2. David Letterman, Oprah, and Uma

You would think that late night host David Letterman would make a superb Oscar host but in 1995, that proved not to be the case. That year, the Queen of daytime television, Oprah Winfrey was nominated for her role in The Color Purple. Uma Thurman was also nominated for the film Pulp Fiction and Dave didn't let anyone forget it. He repeatedly said Uma, Oprah. Oprah, Uma which led to a 16 year feud with Oprah.

In 2005 Oprah appeared on the Late Show with David Letterman to end their rivalry and all was right in the world again.

3. Adrien Brody Forces Himself on Halle Berry

In 2003, there was a shocking upset in the Best Actor category and no one was more surprised than winner Adrien Brody, who starred in The Piano. Brody, rushed to the stage in a euphoric trance. This caused him to grab presenter Halle Berry and make-out with her! The audience laughed uncomfortably and Berry could do nothing but adjust her smeared lipstick when it was all over.

After the ceremony, several Women's Rights groups were angered by Brody's actions. He defended the kiss as a means of taking advantage of a moment he would never have again. Sadly, he was right.

4. Beyonce's Wardrobe Malfunction

In 2009, Beyonce once was performing a choreographed routine with Hugh Jackman and showed off her singing and dancing ability, along with her right breast! The star wore a revealing red outfit that was clearly not secured with double stick tape or body glue. It's unclear whether Jackman or Miss B was aware of the wardrobe malfunction since both of them seemed giddily oblivious to it.

5. Marisa Tomei's Shocking Win

In 1992, Marisa Tomei was nominated for Best Supporting Actress along with screen legends Joan Plowright, Judy Davis, Vanessa Redgrave, and Miranda Richardson. When the winner was announced, many were shocked when Tomei's name was called. Sure she fun to watch in My Cousin Vinny but the shocking upset sparked rumors that her win was actually a mistake! To this day, many believe that presenter Jack Palance, read the wrong name.

Though the actress was nominated again for her harrowing portrayal of a mourning girlfriend in 2002 for In the Bedroom and in 2009 for her role as a stripper in The Wrestler, she has yet to live down the speculation surrounding her win. It's likely that the real cause of Tomei's win was that the four stellar nominees canceled each other out.
