For years, I’ve had a vague memory of an episode of Frasier with three separate plots: one for Niles, one for Frasier and one for Martin. I couldn’t remember anything about it, except that I thought it was hilarious and there may have been an ironing board involved (but I wasn’t entirely sure that I hadn’t just been ironing when I saw it).
Finally – and I don’t know why it took me so long – I thought to Google it. And I found it. It was called Three Valentines and the first bit, Niles’s bit, made me happy.
