Erica is a teacher who works at The Learnin' Barn.
Jay also points out that he doesn't like the name of the school although Gloria does. Erica and Jay don't get along very wel, but since Erica is a hippie she is very happy to pretend she likes him.
Jay tells the Feelings Table that he wants to break the table over "a hippie" (refering to Erica.) as she was annoying him with his happiness.
