This week marks the 40th anniversary of Sesame Street, the greatest and most celebrated kids' show in the history of the known universe.

Its cast of colorful character and innovative use of the medium have made it more than just entertainment for the young ones. It's a children's show that has educated the growing minds of children all over the world. It's a show that has shaped a generation into curious and innovative people. It's a show that could kick the ass of any other children's show on the planet if the two were in some sort of a weird battle to the death, provided that no weapons were involved and Justice League doesn't count as a kids' show.

To celebrate this momentous day in television history, I'm compiling the most interesting moments, memories and characters from the show's 40 years into four special lists for their anniversary week (Why four? Because 40 would break the last ounce of my spirit), starting now with the show's best short cartoons.
