Up In Smoke / Укуренные

Great movie, it only leaves good impressions!
P.S.: I've only seen two of them(((

specifically, which ones?

Part 1: They're just getting to know each other and perform at a punk concert at the end.
Part 2: They arrive in Amsterdam and think about what kind of performance they can put on there.
Part 3: Chong meets Chich's brother.
Part 4: They give all their earned millions to a crazy guy, and then a lot of things happen to them, in the end they end up in a mental hospital =)) Oh yeah, and in this episode, they sell weed that turns everyone into lizards.))

P.S. There are actually five parts ;d
