Jon Hamm's Grandmother Doesn't Like 'Mad Men'

Mad Men's Jon Hamm visited Conan Tuesday night and talked about his cameo on 30 Rock, when he played Liz Lemon's boyfriend who is so terribly handsome he lives in a bubble of illusion where things always go his way. This was Hamm's first encounter with Tracy Morgan, whom he described as a "spectacular form of chaos."

"Everyone should have the experience of meeting Tracy Morgan for the first time," Hamm said. "He goes, 'do you know who my biological mother is?' Uh no, Tracy, I don't. 'Leslie Uggams.' Then he goes, 'do you know who my biological father is?' No, Tracy. 'Burt Bacharach.' So now I'm stuck in this bit...I said, 'I have to go to read-through.'"

Hamm also talked a bit about Mad Men, premiering in its third season August 16. He said his grandmother, a churchgoing lady from a small town in Missouri, is not a big fan of the show. "Her feedback was, 'I don't think you're making very good decisions,' which I think distilled things pretty nicely. I think that's going on the season three DVD case."
