 What we're looking for here is observable behaviour. How does a one-element stack behave after we send it 'pop'. We've stated that the stack should be empty at that point, right? So perhaps the observable behaviour is that it acts like an empty stack:
 
 <ruby>
 specify "should raise a StackUnderflowError the second time you sent it 'pop'" do
   @stack.pop
-  lambda { @stack.pop }.should.raise StackUnderflowError
+  lambda { @stack.pop }.should_raise StackUnderflowError
