You never forget your first time watching Norbit, and for Adam Sandler, that’s an experience he shares with his old chair. So it’s no wonder that Sandler is having a hard time saying good-bye to his brother-in-arms(chair). Sandler stopped by Thursday’s Conan to revisit the musical-comedy stylings that haven’t been a big feature of his career in recent years. He sang “My Old Chair,” a song ostensibly about his old chair, but, indeed, ultimately a Trojan Horse for fart jokes. Because Sandler’s chair may have aged, but his sense of humor never will.
