It'll be a mini reunion for fans of The O.C. when Men at Work's Michael Cassidy is joined by guest star Benjamin McKenzie in a 2013 episode of the TBS sitcom. Cassidy played Zach on McKenzie's Fox soap during the 2004-05 season.

McKenzie will play Bryan, the ex-husband of single mom Meg (Bethany Joy Lenz of One Tree Hill), who is dating Cassidy's Tyler. Things don't really work out as planned between Tyler and Meg when Bryan steps back into the picture.

Other Season 2 guest stars include Peri Gilpin, Seth Green and Jason Lee.
