O Look! Jon Hamm Can Teach You About the Letter 'O'

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?
