Sesame Street is an educational television program designed for preschoolers, and is recognized as a pioneer of the contemporary standard which combines education and entertainment in children's television shows. The Simpsons appeared in the celebrity version of the Sesame Street song "Monster in the Mirror." The Simpsons replace two monsters on a wall painting, and at the end, Homer reprimands Bart (who yells "Hey, wubba man!").
Nancy Cartwright is also credited for voicing Bart Simpson in the 1996 Sesame Street episode Maria In the Hospital Part 1
The Simpsons has also made many references to Sesame Street.
