Nile and Frasier decide to throw a party to celebrate Nile's new painting, but Daphne points out that all of their parties have ended in disaster, so she talks Niles into throwing it with her instead.
Frasier is hurt, and decides not to attend, but when everything starts falling apart Daphne asks for Frasier's help, while trying to keep it a secret from Niles.
The party turns out to be a disaster, when Mrs. Moon comes crashing threw the ceiling with the man who painted the picture.
The end where the bed comes crashing through the ceiling was great, and all of this started when Roz's daughter Alice accidentally wrote her name on the picture.
