After a psychiatrist named Dr. Chinstrap hypnotizes Stan and Mr. Mackey to help get rid of their hoarding problems, they are both sent into Mr. Mackey's dream, which takes place in the 1970s when Mr. Mackey was a child. After being chased by Mackey's bully Billy Thompson, they go to Mackey's childhood home, which Mackey describes as his happy place. While there, Mr. Mackey plays with a few of his toys and watches his favorite childhood show. Billy later arrives to threaten Mackey that he will do things to him that he won't forget on the field trip to Frisco Woods the next day.
