 Meanwhile , Marge surprises Lisa by sending her to a performing arts camp for a week . She eagerly immerses herself there in music and theater , meeting several campers who love to break into song and two guitar @-@ playing hipster counselors , Ethan and Kurt . When Marge takes her home at the end of the week , Lisa has trouble readjusting to normal life and looks for a chance to express her newly awakened creative side . She runs away from home and seeks out Ethan and Kurt in " Sprooklyn " , described by the counselors as the " artistic hotbed of Springfield " . However , she soon learns that they have grossly exaggerated the area , which is really a run @-@ down slum , and that they actually work at a sandwich shop . They sing a song about the difficulties of being an artist , during which Krusty gets beaten up for accidentally announcing he is the prison snitch . Ethan and Kurt encourage her to return to her family and think about trying to make an artistic name for herself when she is older . As Marge arrives to take Lisa home , Ethan and Kurt show off a mural that they have painted in her honor , which takes up an entire side of a building .
