It was 1974, and what looks like a pretty stuffy event came alive when the naked guy ran across the stage!

Time magazine says...

A 33-year-old man named Robert Opal ran across the stage naked just as actor David Niven was about to present the award for Best Picture. Opal, flashing a peace sign, reportedly got backstage using a press credential.

The best part of the clip comes after David Niven regains his composure and says,

"Isn't it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off his clothes and showing his shortcomings?"
