The 2nd county nurse Mary Simpson Sue Ann Langdon replacing Julie Adams blends in nicely. The writers have such flexibility with Barney's intellect. They can make him a total imbecile when is needed in the script. At times it's not realistic how stupid he is. But, it gives the Barney character wings to fly into rare air genius comedy.
It's amazing how good both Mary Simpsons were. Especially odd is a change when their episodes we're so close together..
The date pest theme will be used again with Goober. The Barney wrongly thinking Andy is getting married and crashing with a party will also be used again. With Helen Crump. It's ok when they rehash themes on TAGS. Is almost always works brilliantly each time.
