From Mark Saltzman, who started writing for Sesame Street in 1984:
"Arnie as a film editor—if you thought of Bert with a job in the world, wouldn’t that be perfect? Bert with his paper clips and organization? And I was the jokester. So it was the Bert & Ernie relationship, and I was already with Arnie when I came to Sesame Street. So I don’t think I’d know how else to write them, but as a loving couple."
