Sonny and Tawni are invited on an exchange program to Glendovia because of the success of their Check-it-Out Girls sketch, but refuse to go together due to an unknown argument. When Tawni goes she is shocked to discover that it is a cultural wasteland and that the Glendovians think the characters are real check out girls. Meanwhile, an exchange student impresses a girl Nico and Grady like, and they both think it is because of his mustache. They then wear a mustache trying to impress her, but they get themselves stuck in their own mustaches because of the glue.
