John Mulaney hosted Saturday Night Live this past weekend, and in addition to the comedian/former SNL writer’s terrific presence, audiences were also treated to a bit of a cameo by SNL veteran Bill Hader. While Hader left the show in 2013 and has since gone on to create one of the truly great new TV series in HBO’s Barry, it was a joy to see him back on SNL if only for a brief moment or two. Longtime fans of SNL know that Mulaney and Hader worked closely together when they were on the show at the same time, notably creating one of the most memorable characters in recent SNL history: Stefon.

Indeed, Mulaney and Hader co-wrote each Stefon appearance on Weekend Update. While the character in and of itself is memorable thanks to Hader’s performance, each Stefon appearance was made unforgettable by little additions that Mulaney would throw into the script at the last minute, without Hader’s knowledge.

Since SNL runs off cue cards, many times when Hader was performing as Stefon, he’d be hit with truly insane references he was forced to say as Stefon, thanks to Mulaney’s handiwork. While breaking at SNL is something none of the performers like to do (executive producer Lorne Michaels is notoriously not a fan), Hader cracking up while repeating the name “Dan Cortes” in a Stefon sketch is undeniably hilarious.

So with Mulaney currently one of the best and most popular standups on the planet, and Hader winning a bevy of awards for starring in, writing, and directing Barry, now seems as good a time as any to look back at some of the more memorable Stefon sketches these two comedy powerhouses created during their tenure at SNL—specifically ones in which Hader was thrown for a loop.

Below we’ve assembled a grouping of the best Stefon sketches from Hader and Mulaney’s time at SNL.

Stefon Reveals the Name of Jewish Dracula

This may be the hardest Hader ever broke doing Stefon, and it’s all to do with the name of Jewish Dracula. What a punchline.

Dan Cortese

When Hader returned to host SNL in 2014, Mulaney memorably snuck in multiple references to MTV’s Dan Cortese, which cracked Hader up.

What's a Human Bath Mat?

This was the second appearance for Stefon and debuted in 2010, and while Hader mostly keeps a straight face, watch as “human bath mats” throws him for a loop.

Furkels

This 2010 appearance has the one-two punch of “fat kid with biscuit knees” and “Furkels” aka “fat Urkels.”

Stefon Flirts with Seth

This 2011 sketch not only introduces some serious flirtation between Stefon and Seth Meyers (which pays off beautifully down the road), but also introduces the idea of human suitcases.

Stefon’s Farewell

This isn’t necessarily an example of Hader cracking up, but the SNL team did a tremendous job putting together an unforgettable farewell for the character during Hader’s final season on the show in 2013.

Mulaney's Cameo

Mulaney finally got to appear alongside Stefon when Hader came back to host in 2018, to hilarious results.
