Noblesse oblige. [Nobility has its obligations.]

Whenever you feel the need to post to alt.quotations, and your
posting does not already include a quote added by you in the course of
posting or answering, it is considered good manners to supply a quote
anyway--this is, after all, alt.quotations. This quote is known, and
usually announced accordingly, as an ``obligatory quote''--an
ObQuote for short. In alt.quotations, your wittiness is judged by the
relevancy of your ObQuotes.
