Q: How many Bell Labs Vice Presidents does it take to change a light
bulb?
A: That's proprietary information. Answer available from AT&T on payment
of license fee (binary only).
A': Nearly unanswerable, since the one who tries to change it usually
drops it, and the others call for a planning session.
A": Three. One to get the bulb and two to get the phone number of one of
their subordinates to actually change it.
