"We are not asking that Sesame Street do anything crude or disrespectful," reads the petition at Change.org. "It can be done in a tasteful way. Let us teach tolerance of those that are different."

They were "created to teach preschoolers that people can be good friends with those who are very different from themselves," said a statement.
