Does anyone find the episodes where Lucy Meets The Queen, The Fox Hunt and the Scotland episode to be really bad? It's odd because the episodes that came before and after those are really good but when the Ricardos and Mertz's were in Great Britain it seems the writers couldn't come up with anything interesting. Heck the Scotland episode was just a dream.
No, I don't find them bad (watch The Lucy Show or Here's Lucy for bad TV). That said, I enjoy "The Fox Hunt" the most. Many fans (such as PJ) really like the queen ep because of their own personal interest in royalty, of which I have none, so it's a fair offering to me.
"Lucy Goes to Scotland" is one people seem to love or hate. It gets points for being different (no guest stars - yay!). And there's certainly nothing wrong with it being a dream (the dream sequence in season three's "Ricky's old Girlfriend" is pretty funny).
On balance, I think they were trying to replicate season two's "The Operetta", except the music and dialogue aren't as funny. I'll say this: Fred and Ethel are a hoot as the dragon!
