Matt Damon Sends a Cheeky Fax to Ben Affleck

Continuing to trade barbs all in the name of charity, Matt Damon and Ben Affleck were at it again this weekend.

On Friday, Ben made fun of Matt for not being on Twitter while appearing on "Jimmy Kimmel Live." The duo are promoting an auction for a "double date" with them to support Ben's Eastern Congo Initiative and Matt's Water.org charities.

After his appearance, the "Argo" star tweeted, "@JimmyKimmel - I thank you buddy. And @easterncongo & @water thank you! Matt on the other hand? Matt you there? Right. We will fax you."

In response, Matt cheekily took a photocopy of his bare bottom and sent it to Jimmy, writing, "Dear Ben + Jimmy, Here's my fax: Love, MD."
