Forrest Gump.
So there's this middle aged man waiting on a bus and telling his life story to whichever strangers happens to walk by, and he like fought in Vietnam and got a medal from nixon and showed his ass on national television and became a pingis champion and started a successful fishing company and became a millionaire and gave Nike their slogan and ran across the continent and... Oh, and he's mentally disabled and about to meet his son for the first time because the sons mom is dying of aids.
Absolutely bonkers premise, and such a fantastic movie still today.
