Talk about capping off the most awkward Oscars ever w/ an awkward awards show appearance.
So apparently Kimmel & Damon have had a long running feud...based on a long running gag on Kimmel's show.
His guest (and Damon bff) Ben Affleck snuck onto Kimmel's show...and Kimmel had him thrown off! Even his own audience booed him. Wow.
Watch all the awkwardness here.
