I ran across an old function I had written to take a non-negative integer and append the correct ordinal suffix. (I.e. 'th', 'st', 'nd', or 'rd') Out of boredom, I started golfing. Here's an early attempt coming in at 70 strokes: 

sub num2ord2 {
  my $n = shift;
#          1        2         3         4         5         6         
+7
# 12345678901234678901234567890123456789012345678901234567890123456789
+0
  $n.(qw(th st nd rd),('th')x16,((qw(th st nd rd),('th')x6)x8))[$n%100
+]
}

But... I can do it in 40†... Can you beat that?

† It does generate a warning, however.
