WheneverMatt Damonhas a new movie coming out, many late night fans get excited because that means that the actor’s “feud” withJimmy Kimmelwill continue in some fashion. Ever sinceJimmy Kimmel Live!debuted on ABC in 2003,Jimmy Kimmelhas ended every show by apologizing toMatt Damonfor not having him on, since they ran out of time. Over the years, this back-and-forth between the actor and talk show host has given fans a number of memorable moments, but during last night’s episode, they both tried to bury the hatchet by attending “couple’s counseling.”

Last night’s episode started withMatt DamoninterruptingJimmy Kimmel’s monologue in a covert fashion, before he ended up sneaking onto the show disguised asDr. Phil. ButJimmy Kimmelsaw right through his ruse.Matt Damonwas hoping to promote his highly-anticipated sci-fi dramaThe Martian, in theaters October 2, but, instead,Jimmy Kimmelaired an 11-minute video revealing their “couples therapy” session, which took this rivalry to a new level.

There have been several memorable moments in this longstanding feud, includingJimmy Kimmel’s then-girlfriendSarah Silvermanrecording a music video entitled “I’m F—ingMatt Damon.” That video promptedJimmy Kimmelto retaliate with arevenge videoof his own, entitled “I’m F—ingBen Affleck.” In 2013,Matt Damonhijacked the entire show, while a bound and gaggedJimmy Kimmelwas forced to watch.

While he still has never been “officially” interviewed byJimmy Kimmelyet, the actor has been up on stage a few times. He was first officially invited on back in 2006, but after a lengthy recap of all the times he was booted from the show, they actually did run out of time, causing the actor to “fly off the handle.“Matt Damonhas appeared in a number ofJimmy Kimmel Live!sketches, including Movie: The Movie and even a segment ofMean Tweets, where the actor read a tweet fromJimmy Kimmelhimself.

As you can see in the videos below, this contentious “relationship” still needs a lot of work, but we’ll have to wait and see ifMatt Damonwill finally be interviewed byJimmy Kimmelthis week, as we get closer toThe Martian’s release on October 2.
