Ben Affleck may play the brooding Batman in the new superhero film "Batman v Superman: Dawn of Justice," but that does not mean he can't cuddle with some cute golden retriever puppies. The actor stopped by "The Tonight Show Starring Jimmy Fallon" Thursday night where he and the host faced off in a game of Pup Quiz.

In the game, Affleck and Fallon both had to answer trivia questions that were related to animals. If one of them answered a question correctly, they got to hold one of the puppies, which were all dressed up as superheroes. If they did not answer the question correctly, their opponent got to hold the puppy. "The Tonight Show" announcer Steve Higgins acted as the host of Pup Quiz, all while teasing the contestants with the adorable puppies.

"In the DC Comics series, what was the name of Batman's canine crime-fighting partner?" Higgins asked Affleck, who was up first. "Was it:  A) Rex the Wonder Dog, B) Ace the Bat-Hound or C) Batdog?"

Things got off to a rocky start for the actor, who did not seem to brush up on his animal trivia. He guessed the wrong answer and sent the first puppy over to be cuddled by Fallon. While the host got to hold the first puppy of the night, who was dressed as Batman, Fallon got off to an equally bad start. The former "Saturday Night Live" star did not know the answer to "Which one of these birds is native to the forests of South America," which sent a puppy dressed as Superman over to Affleck.

Fallon then started to pull ahead in the Pup Quiz when Affleck answered a "Double Puppardy" question wrong, meaning the puppies dressed as Wonder Woman and the Flash were sent into the lap of the host. In all the chaos, the mask the puppy Batman was wearing fell off, revealing its true identity.

"You're giving it away," Affleck yelled at the fluff ball.

Fallon then got his next question correct and won Batgirl and Supergirl puppies, bringing his total to five golden retrievers sitting in his lap. The game finally came down to the Final Puppardy question, where the winner would take all.
