Perhaps DiCaprio was stuck by flashbacks of the harrowing attack -- or maybe he just thought the joke was kind of dumb.
Actually, we're going to go ahead and put our money on the "he thought the joke was dumb" theory.
Let's face it, the folks behind Hollywood's biggest night probably should have known better. After all, a similar joke didn't work any better when Jonah Hill and Channing Tatum made it at the Golden Globes in January.
That time, it was Jane Fonda's turn to look annoyed at the shenanigans.
Recently, DiCaprio spoke with ET, where he praised Revenant cinematographer Emmanuel Lubezki, and the bear attack scene in particular, for creating a film that is "groundbreaking cinematically." It seems the Academy agreed, awarding Lubezki his third Oscar in a row.
