+If a manager needs to access its associated class, it should use {{{self.klass}}}. Example:
+
+{{{
+#!python
+class PersonManager(models.Manager):
+    def get_fun_person(self):
+        try:
+            return self.get_object(fun__exact=True)
+        except self.klass.DoesNotExist:
+            print "Doesn't exist."
+}}}
