Teaser: Collecting things to recycle. Main Synopsis: It's time for Jesse to graduate from night school. Michelle suggests that everyone rides a subway train to the graduation ceremony because subway trains don't cause as much air pollution as cars do. Everyone regrets following Michelle's suggestion when electrical problems on the subway train cause it to stall and come to a stop. Because of this, Jesse believes they are going to be late and that the officials at the school would not be surprised to see Jesse miss his chance to graduate. The family, minus D.J., who is out of town, throws a graduation "ceremony" for Jesse on the subway train, which starts moving again after the mock ceremony is over, and it's obvious that Jesse gets his diploma.
