Jon Hamm has claimed that he has "an enormous head" but not as big as Ben Affleck's head.
During his appearance on the show Late Night with Seth Meyers, the 'Mad Man' star said that he was always known for having a giant head but he got to know that the 'Argo' actor has the biggest head when he first visited the SNL for hair and makeup, Us magazine reported.
He further revealed that as he was curious about how much bigger Affleck's head was, he lent him one of his fitted baseball caps, which literally sat on top of his head like a "little toy hat".
