1974: Streaker surprise
David Niven didn't let the surprise appearance by a streaker throw him at the 1974 Oscar telecast. He remarked: "But isn't it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings?"

When Louise Fletcher won the best actress Oscar for the 1975 drama "One Flew Over the Cuckoo's Nest," she delivered her acceptance speech in sign language. Her touching gesture was for her deaf parents.

1989: A 'Snow White' embarrassment
Someday her prince will come, but it wasn't this day when Rob Lowe crooned a tune to Snow White, played by Eileen Bowman, at the 1989 Oscars. Thanks to that number, The New York Times noted that the show had earned "a permanent place in the annals of Oscar embarrassments."
