A promotional video for a charity which features Ben Affleck and Matt Damon has been released online. Promoting a donation drive, Affleck and Damon end up make fun of each other while encouraging fans to take part in the good cause which will also give a lucky fan a chance to hang out with them.

"And you and a friend could win a trip to Los Angeles and stay at a four star hotel and be our very special guest at a very special Hollywood event," Damon says, while Affleck mentions that "it'd be like a best friend double date." Damon then explains, "It'll be like just us, hanging out, taking selfies, talking about how the Sox are gonna do." The "Pearl Harbour" star adds, "Or, if you have more sophisticated interests, we could talk about 19th century literature or the current state of politics in the Middle East..."

"And if like you don't want to get really weirded out by having existential questions posed to you by Ben Affleck then maybe we could talk about other fun stuff like stories from the set of 'The Bourne Identity' or any of the other hit movies that I've been in," Damon says, to which Affleck replies, "Or we could talk about stories from the movie 'Argo' which won Best Picture."

"We could talk about 'Good Will Hunting'. We could talk about who did the bulk of the writing - because I could answer that one," Damon continued saying, to which his friend answers, "Sure, or we could talk about things that are actually true! Like how incredibly short Matt Damon is!"

"Or the fact that Ben's left eye twitches every time you say 'Gigli'," Damon strikes back. The pair then show their backs to the camera and continue bickering.

Last month, Omaze announced that people would have a chance to hang out with the stars by donating $10, which will benefit Eastern Congo Initiative and Water.org. The contest ends on February 18.
