Bert and Ernie's Great Adventures is an animated series developed by Sesame Workshop in which clay-animated versions of Bert and Ernie use their imaginations to travel to strange places and into entertaining situations. The characters' performers, Steve Whitmire and Eric Jacobson, provide the voices for the American Great Adventures segments. Additional voices are provided by Sesame puppeteers Stephanie D'Abruzzo, Joey Mazzarino, and Tyler Bunch. The segment's theme song was written by Sarah Durkee (lyrics), Michael Abbott and Joseph Franco.
