The code I am running is 
#!/usr/bin/perl

use warnings;
use strict;

my $content = qq(Three blind mice.  Three blind mice.  See how they ru
+n.  See how they run.  The butcher's wife came after them with a knif
+e, three blind mice.);
my @words = split(/\s+/, $content);

my @words_bi;

foreach (@words) { print "$_\n\n"; }

foreach (0..$#words) {
   next if $_ < 1;
   push(@words_bi,  [ @words[$_-1 .. $_] ] );

}


foreach (@words_bi) { print "$_\n\n"; }
