If the exception doesn't take any arguments, you can just do

   raise InsufficientFundsError

If the exception takes only one argument you can do

   raise InsufficientFundsError, 123

But if the initialize method takes multiple arguments, as far as I know 
you must create an instance of the exception class explicitly. (Tested 
with ruby 1.8)
