Frasier continues his war with Cam over the American Flag draped past his window, which Frasier realizes he can't really argue, but will try to anyway.
Frasier meanwhile has enough of Simon and throw him out, and after a failed attempt to crash at Roz's house, Simon heads to California.
Daphne has enough of her mother and tells her off, telling her that Simon didn't want to take care of her and headed off to CA.
To make Daphne feel guilty Mrs. Moon fakes an injury, which they later find out about, but in the end Niles and Daphne tell her she can stay as long as she likes.
Frasier takes Cam's American flag to the board and loses, but him and Cam compromise, if Frasier will give up his parking spot, Cam will move it to the roof, Frasier agrees.
I loved the end of the episode where Frasier tried to get everybody to sing along again and no one did, the whole board room scene was great.
