premise: Last night I was watching one of my favourite musicals - Fiddler on the roof . It was probably on the 3rd time I watched the movie and it has probably been at least 5 years . So I ' m watching this great film and the papa starts to sing " If I were a wealthy man ba da ba da ba ... " and I sat there having a total deja vu . Why do I know this song ? Why does this person watch the same movie again and again ?
hypothesis: It is a favorite musical film , it is an iconic film that is important to this person .
