In a new Sesame Street sketch, Zach Galifianakis gets a hard lesson in how to move nimbly

“Zach be nimble”? He gets there eventually.

Of all the adjectives you might use to describe Zach Galifianakis, “nimble” might not be the first one that comes to mind.

That didn’t stop the actor from visiting Sesame Street to help Murray give a lesson in what the word means. Turns out Galifianakis needed it, too, based on his first attempt at moving nimbly. Learning moment!

Galifianakis, 45, is the latest celeb to make an appearance on the PBS educational show. Earlier this year, rapper Macklemore performed a reworked version of "Thrift Shop" with Oscar the Grouch.
