Jeffrey Dean Morgan on Craig Ferguson

What exactly do Jeffrey Dean Morgan and Craig Ferguson have in common? Well, in P.S. I Love You, Morgan played an Irish musician and starred opposite of Gerard Butler, who like Craig Ferguson, is Scottish. Okay, that might be a stretch. Lets go with, they’re both hysterical.

Morgan is well known for his roles on television as Denny on Grey’s Anatomy and John Winchester on Supernatural, but he stopped by the show to promote his upcoming film, Taking Woodstock.
