Kill me now!

gistfile1.rb

def some_method(param)
  foo = nil
  if param
    if param == "value"
      foo = get_foo_somehow
    else
      foo = get_foo_some_other_way
    end
    unless foo
      foo = find_foo
      if foo
        foo = foo.modify
      else
        foo = foo.modify_other
      end
    end
  else
    foo = find_foo_in_yet_another_way
    foo = calculate_foo unless foo
  end
  return foo
end

thankfully there is a return statement on line 21... that clears things up!

Holy McConnell!
