that isn't the only episode in which she tickles him. In one episode called "The Engagement", she briefly tickles him. There is another one, I cant remember the title, where she is helping him design costumes for a benefit and she sits down on the other side of his desk, puts her feet under his desk and takes her shoes off, only to find that he does the same thing. SO, she starts tickling his feet with hers. For those /f lovers, he does it back. You cant see anything, but you can imagine....
Also, there is an episode where the boy gets tickled- its the one where they go to a ski resort to meet the president. When they are entering the building, the insane secret service guy tickles him. ITs really good- he reacts severely.
