A classroom skit that third-graders were preparing to present in a Prince George’s County elementary school was canceled after a parent alerted school officials to material she thought was offensive to immigrants.

The short skit — titled “The Uninvited Guest” — tells a story about Uncle Sam and the people who are welcome at a party in his “Country Haven.” In a nod to the nation’s immigration debate, guests who have lived in the country all their lives and those who have visas are invited to attend, but the Uncle Sam character makes it clear that those who do not have visas — those who “sneak into” the party — are not welcome and must leave.

“Outsiders who pose a threat to the health or safety of my family aren’t welcome here,” Uncle Sam says, according to a classroom copy of the skit obtained by The Washington Post. Uncle Sam berates a visitor who comes in through a window, uninvited, telling him to go back to where he came from. “I don’t want any drug addicts or drug traffickers to come in either. No criminals. We have enough problems; we don’t need to invite more!”
