THE DUNDER MIFFLIN STAFF DEALS WITH SOME SURPRISES AROUND THE OFFICE IN THE WAKE OF CASINO NIGHT When Michael (Golden Globe winner Steve Carell) unintentionally outs a gay employee, he stumbles through a sensitivity mine-field. Also, we find out what happened with Jim and Pam. Rainn Wilson, Jenna Fischer, John Krasinski, B.J. Novak, Melora Hardin, David Denman, Leslie David Baker, Brian Baumgartner, Kate Flannery, Angela Kinsey, Oscar Nuñez, Phyllis Smith, Paul Lieberstein and Mindy Kaling also star.
This is a running joke that never was. Even though Dwight "found out Oscar's secret" last season he obviously never told any one and only the viewers know. Apparently there was supposed to be a running gag where Michael is always calling Oscar a homosexual in various ways to make fun of him. They were all cut and I'm not sure if they show up on the DVD extras.
PS: This show is now a true ensemble. That is one long cast list and doesn't include the warehouse.
