Mr. Hooper the litterbug ('Sesame Street' Wednesday)

Tsk, tsk. How can anyone litter Sesame Street?

Especially the grownup characters like Mr. Hooper, Maria, and David?

Well, litter it they did in this hilarious 1972 sketch:



It's unclear, however, if Bob's newspaper featured an ad for an escort service like that he read in a later skit.

After realizing the error of their ways, residents of our favorite television alley walked backwards, and their discarded litter magically jumped back into their hands. Then all this trash teleported itself into a garbage can that suddenly appeared on the sidewalk.

This no doubt chagrins Bert and Ernie deeply, as the trash can is right outside the window of their apartment.

But Sesame Street has been largely litter-free in the 37 years since.
