At the end of Culkin’s brief cameo, Hamm threw a jab towards his way, saying, “Alright, whatever dude, you know, that Mad Men was better than Succession .” Culkin then parted ways before refuting Hamm’s comments, saying, “I love you, bye.”

"Don Draper was responsible for selling the American dream, and Andrew Cooper's pretty much responsible for buying it," Jon Hamm tells Newsweek.
