This is one of the cleverest episodes. When Hawkeye and Trapper smuggle penicillin to the local orphanage, they tell the nuns that a Captain Tuttle is to be given credit for it. Naturally, there is no Captain Tuttle. And, naturally, this person suddenly becomes real in the minds of all the camp. Because of his "kindness" and our boys' intervention, using records Radar is able to manipulate, he becomes a real person. Margaret immediately falls for him and Frank gets jealous. People who don't know who he is remember meeting him. What is great about this is the double entendre comments made by people concerning their knowledge. The problem is, of course, that at some point he is going to have to be present at something and the ruse will be exposed. The way this is all handled is outstanding writing.
