Dheeraj's code has optional arguments. In such circumstances arity will return a negative number (where -1 means that the method requires at least 0 arguments, -1 would mean a method that requires at least 1 argument etc...
Thanks Dheeraj. Quick question about the pick axe book. Have you given

It was the first book on ruby I ever read
