This is *not* how you need to call a parent class's implementation of a method unless you override that method in the child class.  Specifically:

```py
class Mommy(object):
    def do(self):
        print "mommy's do"

    def stuff(self):
        print "mommy's do"

class Child(Mommy):
    def do(self):
        print "in child's do"
        super(Child, self).do()

    def stuff(self):
        print "no mo of mommy's stuff here"
```
