ET sat down with Pratt and Faris ahead of the Guardians of the Galaxy star's guest appearance on CBS' Mom, where he adorably described his experience working on the sitcom the most enjoyable job of his career.
"This is the most fun I think I've ever had on a set," he said. "It's really nice to see your spouse in their work environment. Well, I don't know if it is for everyone. It is for me 'cause my wife is Anna Faris."
