Niles alludes to a meteor shower "several years ago" that he observed from Frasier's Balcony with Maris. Another earlier meteor shower appeared in "The Seal Who Came to Dinner", where Frasier and Niles threw a dinner party for the Gourmet Club at Maris's beach house, without Maris.
Frasier says this is his first time on a bus. However, he told Niles he went on one at a cocktail party once for the "Friends of Transit" in Season 7's "Back Talk (1)".
Martin: You could have told me we were stopping here when we left for the game.
Frasier: If you'd known that, you never would have agreed to come.
Martin: Well, you didn't have to trick me. I mean, I would never do anything like that to you.
Frasier: It seems someone is forgetting sending Niles and me off to Boy Scout Camp to earn our 'Opera Badges'!
Daphne: Hey Niles! I thought you were working.
Niles: Well, the patient cancelled so I thought I'd drop by and see you. (breathless) Oh my God, you have no idea how good it feels to say that! I'm here to see you! No more flimsy pretenses. No more making tedious small talk with Dad.
Martin: Hey Niles, it's eighty-two in Florida!
Niles: Here to see Daphne, Dad!
Daphne: Well, I'd better check on the roast in the oven. It's three-seventy-five in there!
Title : The Bad Son
The episode title alludes negatively, of course, to the series pilot, "The Good Son".
