ADAM SANDLER hosted “Saturday Night Live” this weekend, and it was his first time since leaving the show in 1995.  He ended the episode with his CHRIS FARLEY tribute song, complete with classic video clips.

He started the show on a musical note, too . . . with a song about how he was FIRED back in the day.  CHRIS ROCK joined him on that one.

Speaking of guest appearances, KRISTEN WIIG and JIMMY FALLEN appeared in a Sandler Family Reunion sketch.

Adam also brought his Operaman character back to “Weekend Update”
