Yes, I am an adult, and I know that I shouldn’t be watching Sesame Street. But the kid in me gets excited over seeing who will be on the series. According to the The Huffington Post…

“Sesame Street” Season 43 will be filled with stars … TV stars to be exact.

“Mad Men” actor Jon Hamm, “House of Lies” actors Kristen Bell and Don Cheadle and more very familiar TV faces will be paying a visit to Elmo and co. when the new season premieres on Mon., Sept. 24 on PBS Kids. Other familiar faces stopping by include “Parenthood’s” Dax Shepard, “Justified” star Timothy Olyphant, Ed Helms, Zac Efron, Melissa McCarthy and Steve Carell, just to name a few.

Season 43 will also see parodies of “The Voice” and “Downton Abbey.”
