Cary Elwes, who you may remember as Westley in the seminal '80s film The Princess Bride, guest stars on Life in Pieces Thursday in another swoon-worthy role -- this time as suave creative writing teacher Sinclair Wilde. As you see in the clip, he's quite fond of Joan (Dianne Wiest) -- er, Joan's work that is -- which gets Joan a bit flustered and her husband John (James Brolin) a little jealous.
Convinced that Mr. Smarty Pants is trying to move in on his girl, John gears up to fight for his lady -- and the way he goes about it is nothing short of hilarious.
