Titre original : Dance With Me, Herman
In order to accompany Marilyn to her school dance, Herman decides to take dancing lessons. He goes to Happy Havemeyer's Dancing School, where he is suckered into signing a ten-year contract for 1500 lessons (at $7.50 a lesson). Herman is under the wrong impression that he is going to become a dancing instructor for the school.
