Language Warning: Late in the video, some clips from Sandler's work get a little saucy with the language.
Comedian Shawn Kohne calls it "The Sandlerverse".
He maps out, in detail how every Sandler movie is related. He even goes so far as to take into account other movies from SNL alumni and his comedy albums as well.
As interesting as this conspiracy theory of the growing Sandlerverse is, it's doubtful this revelation will save us from more movies by Adam Sandler. It almost makes them seem worth it though... almost.
