While NBC is sure to grab ratings from their late night succession coming up, Jimmy Kimmel isn’t going to just let that night slide. 

On Jay Leno’s final night of hosting The Tonight Show, Matt Damon will return, “in theory”, to Jimmy Kimmel Live in a much less “King-of-Comedy-esque” way. 

Of course, Kimmel and Damon have something planned, as one of the best guest-hosts bits on late night, but, who knows, they may just “run out of time”.
