A funny episode that combines perfectly executed slapstick (the gun story) with witty dialogue and - strangely enough - believable emotion. In this show the actors have always been good in expressing heartfelt emotions by means of a single glance, a small gesture rather than a soppy bit of dialogue. Think of Niles' feelings for Daphne (hilarious at first, very touching later on) or Martin's genuine love for his sons despite their huge differences.
In Lilith's final episode the true emotional link between her and Frasier can be detected in a look, a smile or an everyday remark that has more meaning that it might suggest. Their relationship is totally believable, the relationship of two people who once loved each other, couldn't live together but once in while are reminded of what attracted them to each other in the first place. Astonishingly, these characters started as caricatures, especially Lilith. Introduced on Cheers, she seemed a one-episode joke. Both characters grew on Cheers, Frasier developed even more on his own show, but Lilith only had her yearly appearance on 'Frasier'. And yet it worked. Has there ever been a comedy show on which one-dimensional characters evolved so successfully into 'human beings'? I can only think of Lou Grant, but he moved from a sitcom to a drama.
