I am a fan of "Frasier," although the later years (of 11) were not nearly so rewarding as the first four or five.
Season 4 offered two of the funniest shows -- of any TV sitcom -- I've seen:
One was called "Ham Radio". In it, the station decides, with Frasier's urging, to do a live radio drama. Frasier was to direct. He cast the show. Niles did not want to take part because of past experience in prep school under Frasier's guidance. Frasier casts a local British man to play an inspector for the mystery that takes place on the moors of England...and fires him for not being "authentic." That sets up Frasier to not only direct but to "star"...and then the true fun begins. Gil Chesterton has a role that gets cut...including a monologue he desperately wants to recite...and begins many times, each time getting killed off by Frasier before he can finish. Roz has a part, too, but shows up straight out of the dentist's chair where she has received an unexpected root canal and her tongue is still deadened from anesthetic. And Bulldog brings in his current girlfriend who has one line to read -- "He's got a gun!" which she delivers, dyslexically, as "He's got a nug!"
As the play drags on, time grows short, and Frasier continues to cut parts willy-nilly, to the disdain of all. He has badgered Niles into taking a role, which turns out to be something like five small parts, each requiring different voices/accents.
It's a magnificent show and the cast never reached such dizzying heights of perfection as in this one episode.
Another episode involves a gift Martin had received from someone -- a hot foam dispenser. He, or Daphne, puts it in the bathroom just off the entry where, later, after you've forgotten about it, Niles goes...there's an explosion...and Niles staggers out, covered with foam.
It's a priceless sight gag.
In Season two or three, there was the hysterical episode in which the new station manager is invited to dinner by Frasier who has complimented the man's taste in ties, and by gushing over a men's store in London. Frasier thinks he's invited the man for Daphne to meet...but the station manager, who is gay, thinks he's on a date with Frasier, and everyone says things to make him believe everyone in the houshold is gay except Daphne (who has a terrific sight gag at the end with a strapless wire bra).
