Familiarity breeds attempt.Familiarity breeds children.Far-away talent always seems better than home-developed talent.Fill what is empty; empty what is full; scratch where it itches.For every "10" there are 10 "1's".For every action, there is a corresponding over-reaction.For every action, there is an equal and opposite criticism.For every action, there is an equal and opposite government program.For every credibility gap there is a gullibility fill.For every idiot proof system devised, a new, improved idiot will arise to overcome it.
