Jon Hamm Demands Kieran Culkin’s Oscar After His SNL Return Is Interrupted — Hosting Again for the First Time in 15 Years: Watch

The actor last hosted ‘Saturday Night Live’ in 2010

Live from Studio 8H — it’s Jon Hamm!

The actor, 54, hosted Saturday Night Live on April 12, when he was joined by Lizzo, who served as the evening’s musical guest.

“I’m so honored to be here hosting. This my fourth time,” Hamm said during his opening monologue. “It’s been a minute. Last time I hosted was October 2010, but even though it’s been a while, I’ve still been on the show a lot.”

“In fact, I was checking my own Wikipedia, which I often do, and I found out since then, I’ve made 14 cameos,” he continued. “In many ways, making a cameo is even more special than being the host.”

As Hamm watched several of his SNL appearances, he gushed about the audience’s reaction every time he made a surprise cameo, before Kieran Culkin unexpectedly crashed his monologue.

“What are you even doing here? This is my monologue,” Hamm said, to which Culkin, 42, replied, “I know, I’m just making a cameo.”

“Why? I’m a huge star, and I’m doing really well all by myself,” Hamm continued, before Culkin responded, “I’m sorry, man. I’ll make it up to you.”

Hamm then demanded that Culkin give him his Oscar to apologize for the interruption, then prompting a debate over who starred in the better television series.

“Mad Men is better than Succession,” Hamm said, with Culkin arguing, “No, it isn’t.”

“I think we can both agree that you’re wrong. I love you. Bye,” Hamm then stated, before pushing Culkin off-camera.

Elsewhere during the show, Hamm starred in a variety of sketches, including one in which he played a detective investigating a missing person’s case, and another where he poked fun at medication advertisements.

One other moment from the late-night comedy sketch series saw the star portray a participant in an icebreaker, who shares too much information.

During a musical performance, Lizzo, 36, performed a medley of “Love in Real Life/Still Bad” from her soon-to-be-released album Love in Real Life.

She later returned to the stage to sing “Don’t Make Me Love You.”

Ahead of his SNL hosting gig, Hamm told PEOPLE in an exclusive interview that he was excited to return to host the late-night series for the first time in over a decade.

“It’s funny. It’s been 15 years since I hosted, so I’ve forgotten — Am I supposed to be nervous yet? I don’t remember,” he said at the time, adding that it was “a tremendous honor to be asked back.”

“It’s such a unique thing to do in our industry, and in television, and obviously, with the 50th anniversary … and I’m just so honored to be a part of that family, for sure,” continued the Your Friends and Neighbors star.

Hamm last hosted SNL in October 2010. Before that, he hosted in January 2010, and he made his hosting debut in October 2008.
