Kristen Wiig to guest star on ‘The Simpsons’

According to Entertainment Weekly, Kristen Wiig is lending her voice to an episode of The Simpsons that is slated to air on Fox in the fall. In the episode “Homerland,” Homer starts to act strangely polite after returning from a nuclear power plant convention, prompting a suspicious Lisa to ask an intense FBI agent (Kristen Wiig) to help her solve this mystery. This isn’t Wiig’s first trip to Springfield: She’s also played a substitute music teacher who drew the interest of Principal Skinner in a season 22 episode. Great news, huh?
