The Landman actor's fourth turn hosting also brought several fun cameos, including Kieran Culkin and Scarlett Johansson.

Andrew Dismukes led the charge for a group of new hires at a company and asked if they had ever done an icebreaker, with Hamm emphasizing that he “loved them.” He then instructed the group to share their name and a fun fact about themselves.

Jon Hamm is a Saturday Night Live pro at this point. In an exclusive interview with PEOPLE, the actor, 54, says he is excited to return to host the late-night series for the first time in over a decade on April 12.
