What do আপনি think the best episode is with Frasier/Roz interaction, whether its a BFF moment অথবা a love-ish moment, অথবা a 'I'm very frustrated with you' moment?

It's probably the episode moons over Seattle, where Frasier chases roz to Wisconsin after they slept together on guilt trippers. I like there relationship in this because they are able to overcome the problem that they faced and still be friends, this strengths their relationship :)
