responsibility for the completion of the task will invariably protest
that his staff is too small for the assignment.

American wrestlers
-- does it take to change a light bulb?
Three. One to yank the old bulb out, throw it on the
floor, try and jump onto it from a great height, and act
real surprised when it rolls out of the way at the last
minute, one to pretend to twist the new one in round and
round so far it almost breaks, and some guy in a black
and white stripey uniform whose function is never made
quite clear to protest about something or other, to the
complete indifference of the bulb changers....
