So, looks like Bill isn’t on LNSM tonight, but Mulaney is!

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.
