Ben Affleck, Jimmy Fallon act out 'Accountant'-themed scenes during round of Kid Theater

NEW YORK, Oct. 10 (UPI) -- Ben Affleck teamed up with Jimmy Fallon on The Tonight Show recently for a round of Kid Theater based on the actor's upcoming film, The Accountant.

The game which consisted of Affleck and Fallon acting out scenes written by children, started with the pair imagining themselves as a boy and girl who can't decide whether or not they want to be an astronaut or an accountant.

"I got it! You could be an accountant who wears an astronaut helmet!" Fallon explains as a little girl. The scene ends with the characters both becoming accountant astronauts who later reunite on the moon.

The last scene involved two accountants having dinner together before almost coming to blows after they disagree on which number is the best.

"Wait, what are we doing? We are accountants. We promised to never fight other accountants," Fallon explains to end the feud. "Of course, the accountants oath," Affleck chimes in before both then raise their hands to their hearts to cite the oath.

The Accountant which also stars Anna Kendrick and J.K. Simmons arrives in theaters Oct. 14.
