Out with Dad is without a shadow of a doubt my favourite Frasier episodes. Frasier has taken fancy to a woman who he meets at the opera regularly. To give him moral support Martin tags along with him. The woman brings her mother who takes a fancy to Martin and to avoid hurting her feelings he tells her he's gay. The mother then thinks that he would be ideal person for someone she knows to go out with. After Frasier manages to convince the woman he likes to come back to his apartment so Martin,the woman, her mother all go back to his apartment and the mother's gay friend tags along(following so far). The gay friend tries to hit on Martin and Martin is none the wiser. Then when it suddenly dawns on Martin what's going on he lies to the gay friend and tells him he's actually dating someone and at this point Niles walks into the apartment and for some inexplicable reason Martin declares Niles is his boyfriend, cue lots of hilarity Frasier style. It's episodes like this one that remind fans why they started following Frasier in the first place. Top notch episode from a top notch sitcom.
