Ben Affleck and Matt Damon are the greatest Oscar-winning best friends of all time. Although, after last night, Kate and Leo are running up on them--real quick.
But on Jimmy Kimmel Live's post-Oscars show, Ben and Matt took their friendship to the next (and if we're being completely honest here--logical) level when Affleck snuck in the blacklisted Damon like a marsupial mama.
Under his ridiculously large coat.
They have fun. Kimmel, however, was having none of it, and had Damon promptly escorted out of the studio, presumably to hang out with the rest of the night's losers.
