He doesn't need to be chain smoking on Mad Men to be entertaining!
Jon Hamm recently went on down to Sesame Street yet again, but this visit happened to be O so special!
The handsome fellow was quizzed by the beloved character Murray on the letter O, and all of the words that go along with it!
And like he does with so many of the women on that 60's period show - he nailed it!
It was incredible! He was on an O roll!
