murphy's law

who is this 'murphy' character that writes these 'laws'?
i'd like to get my hands on him.
is he irish? he sounds irish.
but then where does the saying 'luck of the irish' come from?
isn't that kind of contradictory?
not that murphy necessarily represents all of the irish, but he seems to have a lot of pull.
he certainly messes with my life on a regular basis.
not today in particular.
but he does fuck with things a lot.
maybe i should look at the end of the rainbow.
little irish bastard.
