— RainnWilson (@rainnwilson) February 24, 2014"The Office" actor B.J. Novak appeared on ABC 7 Chicago’s "Windy City Live" today and recalled working with Ramis.
“He was a very beloved member of the extended family of 'The Office,' says Novak. "He was funny and warm and slightly lazy….but he was the first to tell you that! He’s like 'I’m a little lazy, I’m going to sit in this chair and let you guys do your thing!'”
Novak continued, “He gave the most insightful suggestions. He really knew human nature very well and that’s what made him so funny. I think 'The Office' was very much in the shadow of a style that he helped pioneer in which comedy really comes from honesty and honest emotional portrayals of real people being their best and their worst.”
