Dial M for Martin

Plot:

With Frasier home all day, he and Martin get into explosive arguments. Roz suggests that Martin move in with Niles for a while. Niles is as enthused at the idea as Frasier was six years before, but changes his mind rapidly when he realizes Daphne will be coming too. Then she announces that Martin's hip has improved enough for her to find another job. After a series of minor accidents, Martin becomes afraid that Niles is trying to injure him on purpose.
