Jon Hamm has it all. He's talented, handsome and he really knows his alphabet.
Hamm stopped by Sesame Street to help out Murray Monster with his letters -- specifically the letter 'O'. After all, Hamm gets to use all his vowels -- and some consonants, too -- while playing the brooding Don Draper on AMC's Mad Men.

Of course, Hamm is a lot more cheerful (and scruffier) than the mysterious ad man he plays on TV. Who knows how many 'O' words Don Draper can name?
