I'm making a Eightball script for my AI I think people would love to use. I just don't know how you will get the random to actually work.
In AIML a random tag gives one of the elements at random.
Bot Libre also lets you add multiple responses to a question and chooses one automatically.
How are you? I'm okay. I am great! Not so good.
Self also has a random() function.
How are you? Template("{random ("I'm okay.", "I am great!", "Not so good.")}")
