So, I'm sitting there watching some episodes from Season 4 or Season 5 (because I barely watched those seasons when it originally aired), and suddenly I see someone who looks familiar.
"Holy crap! Is that Bobby?!"
And yes, yes it is. I had no idea Jim Beaver had a little recurring role on 3rd Rock. He plays Harry's boss at the bar, Doug. Crazy! He could use his "You are either insane or an idiot" expression on 3rd Rock too.
