Martin dismisses Frasier's call to the police as being frivolous, however, in reality, forgery is a serious crime, especially when there is a great deal of money involved. The gallery would have been subject to criminal charges if they had knowingly sold a forgery, and Frasier could have easily won any court action against them. It's also unlikely that Martha Paxton would have let the matter go.
When Frasier pondered how to get even with the art gallery that sold him the forged painting, he considered talking about his experience with the art gallery on his radio show. Niles cautioned him that doing so would be slander, and the gallery would sue Frasier for everything he owned. What Niles said about slander was a factual error. A truthful statement is not slander in the eyes of the law. Frasier would have been telling the truth on his show -- the painting the gallery sold him really was a forgery. Therefore, his story about the gallery would not be slander. This means the gallery would lose a slander lawsuit because there was no slander. It would have been impossible for the gallery to sue Frasier for everything he owned.
In the opening scene, Frasier begins to sing: "When the moon hits your eye, like a big pizza pie..." He is pretty poor at it (which could in itself be a goof, as he is reputed to be a fantastic singer), and it gets people to call in. Unfortunately, Frasier cuts off right at the beginning of the song (as above) to take his first call, which Roz has miraculously been able to ID already. However, KACL is on a seven-second broadcast delay (as we learn in "Call Me Irresponsible"), so even if Roz had not taken the time to screen the caller for name and dilemma, the man would have had to call in before Frasier began to sing.
Frasier: I hate lawyers.
Niles: Oh, me too, but they make wonderful patients. They have excellent health insurance, and they never get better.
Daphne: Oh yes, I'm getting a feeling. It's in your father's room. No, no, it's in Dr. Crane's room. Oh, this is odd, now it's in the hallway.
(Eddie scampers in from the hallway and across the lounge)
Frasier: "Live with my work"--I love that phrase. If you would, right this way, please. (leads her towards the center of the room) I think this is the perfect spot for an ideal viewing. Oh God, I've waited so long for this moment--I'm just going to stand back and let you describe your work, Elegy in Green,in your own words. The way you insinuate the palette but never lean on it, you capture the zeitgeist of our generation. It is the most perfect canvas it has ever my privilege to gaze upon. I mean, one can only imagine what inspired you to paint it.
Martha: I didn't paint it.
Frasier: May I take your... poncho?
Martha: No, no, no, no, I never take it off at parties. It gives me an excuse not to shake hands with people.
Frasier: Oh, how delightfully eccentric! You must meet my brother, Niles. Oh, Niles?
Frasier: Oh hi, Roz, it's you. (she looks offended) And you look radiant.
Roz: I look like crap. I've got a spot on my dress, I over-plucked one eyebrow and the crotch of my pantyhose is creeping down to my knees.
Frasier: No, I'm just a bit on edge, I want everything to be so perfect. (pause) By the way, where's Maris? I haven't seen her all night.
Niles: She's on your bed.
Frasier: My bed?
Niles: Yes, she's asleep under the guests' coats. She exhausts easily under the pressure to be interesting.
Frasier: Niles, she's supposed to be looking after Dad. That's the only reason you're here, remember?
Daphne: Well, my theory on death is: first you're whisked down a long dark tunnel towards a beautiful white light; you suddenly get all the jokes you never got before, you let out a little chuckle, and then you die!
Frasier: You're listening to KACL 780 on your AM dial. This is Dr. Frasier Crane. All our lines are open, so please, give us a call. (silence) I'm just sitting here waiting. (silence) Hey, Seattle, c'mon, I know you're out there. Hey, look, I realize it's a sunny day but on all those rainy days, I was there for you. (silence) Well, alright then, if that's the way you want it, you leave me no recourse...(clears his throat; singing) When the moon hits your eye like a big pizza pie....
