Managers

I remember the conversation--monologue, actually--in which my then-supervisor, without a trace of irony, assigned me 3 different absolute top priority tasks in the space of 5 minutes. (One involved working closely with someone who was out of town...)

Other people can better that anecdote. I don't have the flier anymore, but the then-principal of our local elementary school sent home a half-page announcement that had several spelling errors and a grammatical glitch.
