What is your fave episode of this show and why?

i dont have one

Isn't It Romantic?
hannah (concerned that the "magic" has escaped their relationship--mirroring the concerns of the critics, AND the show's supposedly perceptive audience) challenges marty that he could not rekindle their passion EVEN IF he surprised her with an orchestra in her living room; THEN he subverts her primary premise (contending that convivial, symbiotic nurture embodies its own passion!) --- and when she succumbs to his (admittedly, lame geektoid) wooing --- he fulfills her conjectured fantasy.
THIS was the most inventively romantic sitcom episode i enjoyed during the '80s. (hey... it was the eighties)

When Hannah turned 30. My favorite only because that's the only one I have a recording of.

Where the Richard Lewis character is talking to a fitness runner and telling her why he doesn't like to exercise!!
