Another preliminary round.
Dad's Art That Aint in Heaven S4E8:
"Martin accompanies Frasier and Niles to their favorite restaurant, where Frasier heaps praise on the hideous paintings that the owner has bought to secure a good table. Martin and the boys get into a fight over who should pay the check. Later, Martin feels bad and makes up by buying Frasier one of the paintings. Frasier can't bear to tell him the truth. Meanwhile, Niles's spineless side is on display in response to Maris's underhanded tactics to draw guests away from a party he's throwing on the same night as hers."
Juvenilia S9E14:
"Kenny announces to Frasier and Roz that some recent research into KACL listeners shows that Frasier's average listener is an older gentleman who keeps the radio on for company. He suggests Frasier reach out to the youth, by appearing on Teen Scene; Frasier, who appeared once before on that show, refuses initially, but when approached for an autograph by a young woman working for a hospice, he reluctantly consents. The representative of the Teen Scene panel whom he meets first, Emily, seems very intelligent and pleasant. Things change drastically when the show starts, and the panel asks Frasier numerous probing questions about his personal life. Fortunately, Kirby Gardner, who went to the same school as the panel members, is on hand to help out by providing Frasier with embarrassing information about the trio. The next day, Frasier enacts his revenge against Teen Scene, embarrassing all three of them. Meanwhile, Niles decides to steal a street sign with Daphne's name on it as a romantic gesture. Daphne discovers that Martin kissed a woman named Peg at a work party, and although he insists that it was nothing special, he spends a few days waiting by the telephone in case she calls."
