This is the opening title sequence to Yes Minister.
And this is the opening title sequence to Yes, Prime Minister.

No, not the totally different (brilliant) animations (the way the 10 morphs into Humphrey and Hacker is delicious).
Why is the first show called Yes Minister, while the second is called Yes, Prime Minister?
I imagine there’s a good grammatical reason, but that comma just makes the title sound either a little more exasperated, or a little more respectful, depending on how you say it.
