The weird thing is I grew up watching Michael Chiklis in The Commish, so I was used to seeing him as a jolly family man. I was also shocked to learn he was only in his twenties when he did the Commish.

Yeah, that was before he started working out to do "The Shield". Back then, he was fat and balding and looked easily 10-15 years older than he was. He was almost the Paul Giamatti of the early-90s, IMO.
