The sketch was written by Mikey Day, who plays Butt-Head above, and Streeter Seidell. A pair who—according to cast member and host of the sketch, Heidi Gardner—have been wanting to do this for a while.
“It was a sketch that had been put up at table reads and rehearsals for about five years prior to this,” Gardner told Vulture in a new interview. “Previously, I was in the sketch but as an audience member. I can’t remember the other castings of it. It never made it to a dress rehearsal.”
This week though, it didn’t just make it to dress rehearsal, it made it to air. “Every so often, because of timing or the stage it’s in, a sketch might be cut on a Friday night as opposed to a Saturday. That’s what happened the time before,” Gardner continued. “I had never seen the costumes. It was a sketch that Mikey Day and Streeter Seidell kept on pitching, like, ‘Before the end of our time here, we have to do the Beavis and Butt-Head sketch.’ It was their white whale; they really wanted to do it. Knowing Ryan is always so down for fun and playful things, my guess is they thought he would be into it.”
I thought it was funnier because they broke character so often. That Butthead costume was 🎯. How could you not laugh?
