It's a Mitzvah, Grover!

It's a Mitzvah, Grover! is a Sesame Street storybook. It was one of a series from Kar-Ben Publishing of Shalom Sesame cross-overs in which the American Sesame Street characters learn about Jewish holidays, traditions, and culture with their Israeli friends from Rechov Sumsum (in much the same fashion as the Shalom Sesame video series).

While visiting his friends on Rechov Sumsum, Grover learns about the concept of "tikkun olam" (repairing the world, which in this case includes cleaning up a playground) and the definition of mitzvah (in this contact, an act of kindness or good deed). Even Moishe Oofnik fins himself doing a mitzvah through his recycling.
