#14 Random Joke Generator
The first thing you learn in public speaking is to start off with a joke. So let's start off with a short program that throws up a random joke every time it's run.
The Code

7 use CGI::Carp qw(fatalsToBrowser);
8 use HTML::Entities;

10 # Untaint the environment
11 $ENV{PATH} = "/bin:/usr/bin";
12 delete ($ENV{qw(IFS CDPATH BASH_ENV ENV)});
