In honor of National Poetry Month, we dug up an animated video of children’s author Shel Silverstein performing his poem, “Ickle Me, Pickle Me, Tickle Me Too.”

The poem was included in Silverstein’s celebrated collection, Where the Sidewalk Ends. It was originally published in 1974 and dedicated to children’s books editor Ursula Nordstrom.

Since the poet died in 1999, HarperCollins has published two volumes of Silverstein poetry. What’s your favorite Silverstein poem?
