What interrupted Jennifer Lawrence's presentation of the best actor trophy?
That would be Ellen DeGeneres and the cast of "Dallas Buyers Club."
As the "American Hustle" actress waltzed on stage, DeGeneres cautiously exited, making sure last year's best actress winner didn't take another tumble before DeGeneres, who had earlier teased Lawrence about falling, got off stage.
While most of the crowd didn't catch the joke, Jared Leto, Matthew McConaughey and their cohorts laughed loudly, causing Lawrence to go off script.
McConaughey had the last laugh.
He won the best actor prize seconds later.
