“There’s a lot of the people from the first five years, and all these different generations. They have this one experience in common — that all looks the same and feels the same and the process is the same,” creator Lorne Michaels exclusively told the Post. “We have 80-year-olds working with 20-year-olds, and you won’t find that anywhere else other than the US Senate.”
