A man phones a mental hospital and asks the receptionist if there is anybody in room 27. She goes and checks, and comesback to the phone, telling him No, the room is empty. "Good," says the man. "That means I must have really escaped."

Bosses versus workers
When I take a long time, I am slow.
When my boss takes a long time, he is thorough.

When I don't do it, I am lazy.
When my boss doesn't do it, he's too busy.

When I do it without being told, I'm trying to be smart.
When my boss does the same, that is initiative.

When I please my boss, that's brown-nosing.
When my boss pleases his boss, that's co-operating.

When I do good, my boss never remembers.
When I do wrong, he never forgets.
