By the end, Bo does feel better because he has such good friends. It's true that he can't do his work, but inside, he feels better.
A lot of these balcony dialogues are slightly altered versions of actual MS scenes. I remember that there was an early S&W gag (maybe from season 1 or 2) similar to the "I don't get it" gag that I used.
: I love French singers!
: I love French fries!
(pauses): I don't get it.
: Well, you didn't order any.
