I saw this in someone's post: 


@monthPost = (
"-", "st", "nd", "rd", "th", "th", "th", "th", "th", 
"th", "th", "th", "th", "th", "th", "th", "th", "th",
"th", "th", "th", "st", "nd", "rd", "th", "th", "th",
"th", "th", "th", "th", "st"
); 

$textInput = "$mday$monthPost[$mday]" # etc.

and it reminded me that I once set off a little golf on that topic. The winner was this (sub) from Jonas Nilsson: 

$_[0]=~/1\d$/?0:qw(0 st nd rd)[$_[0]%10]or'th';
