Nearly a decade ago, Jimmy Kimmel, the fresh-faced host of the relatively new late-night show Jimmy Kimmel Live, had a particularly lame night. Though he felt discouraged by his lineup of less-than-stellar guests, he managed to end the night with a solid joke: “I want to apologize to Matt Damon. We ran out of time.” The joke was so solid, in fact, that Kimmel began ending every single show with the quip, thus beginning one of the most hilarious feuds in television history.

Try as he might, Matt Damon just can’t seem to land a guest appearance on Jimmy Kimmel Live. The schedule bumps have led to some animosity between the two, and over the years, there have been viral videos, poorly-timed fire alarms, and awards show surprises, but one thing’s for sure: the foemance between Matt Damon and Jimmy Kimmel is the gift that keeps on giving.

In honor of Matt Damon crashing the set dressed as Tom Brady last weekend, EW has rounded up the greatest moments of their epic feud.
