Rachael Leigh Cook was 6 months pregnant when Season 2 ended production in 2013; she spent most of her scenes during Season 2's last episodes sitting or carrying files that cover her bump.
At 42:41 minutes into the episode, Jimmy, who is an aphasiac, is watching President Bill Clinton's recording of denying having sexual relations with Monica Lewinsky. He laughed as Bill was lying. That very same video footage was used in season 1, episode 4 of "Lie To Me", where Bill's hand gesture and eye location are not in sync, which is another signature of lying.
Eric McCormack and Kelly Rowan previously co-starred together in the short lived TV series "Lonesome Dove: The Outlaw Years." in Canada in 1995-96.
Scott Wolf and Dan Lauria were in "Party of Five" together.
