Zach Galifianakis Visits ‘Sesame Street’ to Learn About the Word ‘Nimble’ From His Friend Murray and a Piranha

Comedian Zach Galifianakis made a recent visit to Sesame Street to learn about the word “nimble” from his friend Murray. Galifianakis is supposed to act out Murray’s new nursery rhyme “Zach Be Nimble,” but he doesn’t know what the word means. Thankfully, Murray enlists a helpful piranha to get the point across.
