Okay, so maybe actor Robert De Niro DOES know what a dog is.

Nevertheless, the Oscar-winner — not surprisingly — was quite convincing when he stopped in to Jimmy Fallon’s Tonight Show to promote the Tribeca Film Festival.

Watch the clip as De Niro and Fallon happen upon a few people hanging out with a super-cute Labradoodle puppy!

And if you know which film the “cat betrayal” reference is from, tell us in the comment thread! 🙂
