If you don't pass in an array of answers it will use the traditional ones.

sub ask {
    my $question = shift || return "You must ask a question!";
    my @answers  = @_;

    unless (@answers) {
        my $pos = tell DATA;
        @answers = map { chomp; $_ } <DATA>;
        seek DATA, $pos,0;
    }
    return $answers[rand @answers] unless $CONSISTENT;

    my $hashcode = 0;                                                                                                                                       
    $hashcode   += ord($_) foreach split(//, $question);                                                                                                        
    return $answers[$hashcode % scalar(@answers) - 1];
}
