I started reading the Wikipedia page but it was a bit dull. I did like this bit about Kevin Costner though...
This exchange caused the local audience and journalists to realize that Smith's reaction was genuine. Kevin Costner, who waited offstage to present the Academy Award for Best Director, said: "Oh, that was real."
I realized the page kept going and going and going. It's 5,000+ words long. So that was enough of that.
