As any Saturday Night Live fan knows, the cast forms something of a fraternity, it seems like many are life long friends, often appearing in each other's TV shows, films, etc. Adam Sandler recently wrote a funny yet heartwarming song about his late friend, the incomparable Chris Farley who died back in the late 1990s. Well, Adam was at it again this week, appearing on Jimmy Fallon's tonight show to celebrate Jimmy's five year anniversary as host of the show. Below are videos from both this week on The Tonight Show and the song Sandler did for Farley! Turn in up and enjoy it loud!
