    The returned object has a dictionary style interface except that it returns
    a zero count for missing items (instead of raising a :exc:`KeyError` like a
    dictionary would)::
 
-        >>> c = Counter(['if', 'your', 'peril', 'be'])
-        >>> c['questions']                          # count of a missing element is zero
+        >>> c = Counter(['egg', 'ham'])
+        >>> c['bacon']                              # count of a missing element is zero
         0
 
    Assigning a count of zero or reducing the count to zero leaves the
    element in the dictionary.  Use ``del`` to remove the entry entirely:
 
         >>> c = Counter(['arthur', 'gwain'])
-        >>> c['arthur'] = 0                         # set the count of "arthur" to zero
-        >>> 'arthur' in c                           # but "arthur" is still in the counter
+        >>> c['arthur'] = 0                         # set the count of 'arthur' to zero
+        >>> 'arthur' in c                           # but 'arthur' is still in the counter
         True
         >>> del c['arthur']                         # del will completely remove the entry
-        >>> 'arthur' in c
