Susan tells a joke in the workplace: "Why did O'Malley walk into a bar? Because he's Irish!" Her Irish co-worker, Conan O'Brien, is offended by the joke's implicit punchline, the harmful and unfair stereotype that Irish people are alcoholics. Conan doesn't quit his job, and Susan does not make any other jokes or comments about Irish people. Can Conan sue Susan and/or their employer for race and/or national origin discrimination? A) No. Irish people are not a minority in the United States.

B) Yes. Susan has created a hostile work environment for Conan.

C) No. Susan's joke is appropriate, and she can keep telling similiar jokes without creating a hostile work environment.

D) No. Susan's joke is unlawful, but is alone not actionable.
