Stan may have a hoarding problem.His locker is completely messy and he does not want to throw anything away.His girlfriend Wendy is worried about him.He visits Mr Mackey, the school counselor who also seems to have a hoarding problem.A doctor then decides to find the root of Stan and Mackey's hoarding problem by looking through Mackey's subconscious.However, Stan gets trapped in Mackey's subconscious and the doctors call the dream infiltrators(like the ones from Inception) to rescue them.Meanwhile, Mackey's subconscious dream is him as a child in 1974. The younger version of Mackey and Stan are trying to find the root of Mackey's hoarding problem.The episode spoofs the reality TV series "Hoarders"(which I have not seen), and the movie "Inception"(which I thought was fairly good albeit a tad overrated).The episode has some very hilarious moments as well as a scene where something happens to Mackey which may be seen as depressing or messed up.Overall, this is an excellent episode.
