From the ethics exam I took for work today:

Instructions: Click on the best answer below:
Keith and Todd were wrong to try to block a job candidate because of his race. Which of the following would also be inappropriate? -Sending anonymous notes to their supervisor that say:
"Retire! Old people belong in nursing homes!"
-Leaving threatening notes for an employee they believe to be gay.
-Singing the theme song from Shaft whenever a black coworker enters the room.
-These are all inappropriate and don't belong at work.

The rest were almost as good. Makes me wish I knew "Shaft"!
