class String
  def shuffle() split('').sort_by {rand}.join end
end

def munge s
  eac_wor_ = /[a-z]+(?=[a-z])/i
  s.gsub(eac_wor_) {|s| s[0..0]+s[1..-1].shuffle}
end

while gets
  print munge($_)
end

__END__
the only bit of magic is the regexp;
  it relies on the left-to-right matching
  to match the first character of a word greedily
  up to the next-to-last (hence, eac_wor_).

this was great fun! regular expressions are always a hoot and a half
