When Freddie mentions the time Frasier and Niles gave up a restaurant after just 1 day, it was a nod to the season 2 episode of the original series 'The Innkeepers'. The brothers buy Orsini's, restaurant. Renamed Les Freres Heureux (The Happy Brothers), they embark on a disastrous evening which ends with the sprinkler system going off and Orsini's elderly waiter Otto in his new role as valet, driving a customers car through the wall into the restaurant.
