10. Adrien Brody wins best actor for "The Pianist" in 2003

Adrian Brody's best actor win was a talker -- because he planted a big kiss on presenter Halle Berry when he got on stage. Berry has since said about the kiss on "Watch What Happens Live," "I was like, 'What the f**k is happening right now?' That was what was going through my mind." But she gave him a pass, saying, "And because I was there the year before and I know the feeling of being out of your body, I just f**king went with it."

9. Sandra Bullock wins best actress for "The Blind Side" in 2010

Sandra Bullock joked to the audience, "Did I really earn this, or did I just wear you all down?" But the actress got serious as she thanked all of her colleagues and said about the movie, "I would like to thank what this film is about, for me, which are the moms that take care of the babies and the children no matter where they come from. Those moms and parents never get thanked. I, in particular, failed to thank one. So ... if I can take this moment to thank Helga B. for not letting me ride in cars with boys until I was 18 because she was right."

I was probably eight and staring into the bathroom mirror. I feel very fortunate to have made it all the way from there to here."
