When Stephen congratulated George on their upcoming one-year wedding anniversary, he responded, "They said it wouldn't last."
Colbert also asked how George felt about the relationship, saying, "What is it like to be the arm candy in a relationship, because she's the very serious person? She must say like, 'We're going to meet extremely intelligent people tonight -- these are not show folk.”
Clooney answered the question by saying, "Just be shiny and pretty. That's mostly what I do.”
George also made the audience laugh while promoting a fake movie called “Decision Strike.”
