... Sesame Street! See that one coming?

Even if you feel like you’re too old for the long-running kids show, you aren't - especially if Grey's Anatomy's Sandra Oh makes an appearance (date TBD).

Other notable guest stars for the 39th season of Sesame Street include Neil Patrick Harris, Will Arnett, Feist, LL Cool J, Johah Hill, Molly Shannon and Jessica Alba. Fellow Grey's Anatomy star T.R. Knight has appeared in the past!
