Well bart was taking some drugs that made him go crazy , the whole episode was a really funny look at how drug companies dose pople up on drugs for example marge said after bart had started acting strangley (he thought that a basball team was reading his thoughts from a satilitte) that he should come off the drugs when talking to some drug company employees, they then said oh you just can't come off them and then discussed about 10 other drugs he will have to have to get over withdrawl etc etc. bart then excaped and marge got distressed and then what happened, two needles came from the ceiling which said valium on a big sign and injected valium into marge and homer . Ohh how I laughed :lol:
Another funny part of the episode was the fact that bart was telling the truth about the basball team reading his mind!!
