What's with the numbers?

Hey, there seems to be some mix-up with the question numbers and that in turn seems to have led to a bit of confusion.
It's mostly because Pai does weird stuff. But don't blame the freak. Actually, no. Go right ahead. He deserves it. Stupid confusion causing boy. Tch.
In any case, these are the recent confusion-addled questions. Click on the links, read the questions (google if you must) and then answer them.

665 (Newly added question)
666 (Because Pai insists his numbering can't be altered)
667(His opinion isn't that relevant)
668
669

That is all.

Question 669: Even if its his life, he still has a day

The supposed origins of this phrase dates back to the 16th century. In spite of contradictory conventions applied to the __X__ in the phrase __Y__, it still remains amongst the most popular cliches in the world.


A supposed origin is from the lawyer George Graham Vest's tear-jerking speech that became known as the Eulogy to __X__:


"Gentlemen of the jury, a __X__ stands by him in prosperity and poverty, in health and sickness. He will sleep on the cold ground, where the wintry winds blow, and the snow drives fiercely, if only he can be near him. He will kiss the hand that has no food to offer; he will lick the wounds and sores that come in encounter with the roughness of the world. He guards the sleep of his pauper master as if he were a prince. When all other friends desert, he remains. When riches take wings and reputation falls to pieces, he is as constant in his love as the sun in its journey through the heavens." 

The New-York Literary Journa states in Volume 4, 1821:

The faithful __X__ - why should I strive
To speak his merits, while they live
In every breast, and __Y__
Does often at his heels attend.

SO:
ID X & Y 

Question 668: Love thy master

Sitter, I expect.
