"It was a dream to be a part of that theater," Odenkirk said. "And Farley was in the cast and he had done a voice like that in an improv sketch. He was like a coach, you know, 'Come on kids, let's go!' And it was just a go-to voice for him. And I went and wrote this thing about a guy living in his van down by the river and he just killed it every night. It was an amazing thing to see."
