Priest: (on TV) We are gathered here today to join together Joanie Louise Cunningham and Charles, Chachi-Chachi-Chachi, Arcola in the bonds of holy matrimony.
Rachel: See! But Joanie loved Chachi! That's the difference!
Joanie and Chachi, played by Erin Moran and Scott Baio, were the main characters from the TV show, Joanie Loves Chachi, which was a spinoff from the popular TV show, Happy Days.
