I don’t think that everyone can agree to this. Religious folks are apt to claim that this or that prophet was perfect. And I doubt you could’ve gotten many folks in Stalinist Russia to admit to any flaws in Stalin, at least not out loud.
Did you ask Michael Eisner?
How are you defining “principle”? Would a proof in geometry count as a principle? Or does it have to be something with moral dimensions?
Do they? I thought they received oxygen through the umbilical cord.
What they receive is oxygen-enriched blood. But they don’t get anything out of the embryonic fluid.
What don’t you remember?
They do get 02 from the cord, but ‘breath’ the fluid, that I think I may have misnamed.
Yeah, that occurred to me. However, in the case of Christians, one might add the stipulation “borne of man and woman” (i.e., not the result of immaculate conception). In other cases, perhaps similar qualifications can be added. Perhaps it should be modified to be I’m not perfect.
Nonetheless, in the situation given in the OP, there are two notable things: (1) it’s asking for a principle, which I think is a bit weaker than a universal and (2) it’s taking place after death. In the case of (1), we can derive some further useful ethical principles (e.g., just because Robertson/Phelps/Dawkins/etc. says so doesn’t mean they’re right; therefore, one should always retain a modicum of skepticism. Additionally, one should not subscribe to blind faith, nor should one be unwilling to examine one’s own beliefs). As to (2), it removes the Stalinist Russia example (or other coercive scenarios).
The designated hitter is an abomination.
If I have learnt anything, it is that I know nothing.

Plus, I think “And this, too, shall pass.” is not only a pretty good universal truth, but quite possbily the only one.
I would have said “Nothing means anything.” but I think I’d be questioning my atheism once I faced the Owl God. (“I don’t believe in the gods!” “No, but the god believe in you”.
“The Lord loves a workin’ man/Don’t trust Whitey/See a doctor and get rid of it” is pretty much all you need to know to get through life, if you don’t mind being a bit of a jerk. 
I tried this for awhile, but being white myself, it led to an anti-solipsist position that was completely untenable. 
Not sure “I’m not perfect” works either. Their are doubtless half a hundred religious nut jobs out there who think they are perfect. David Koresh, for example, thought he was Jesus come again, so I presume that would include thinking he was perfect.
I don’t think that everyone in totalitarian states belive the hype about thier various leaders purely out of fear for thier lives, though. Propaganda becomes a sort of state religion, and the people do end up thinking their leader is perfect. As an example, I watched a PBS special a few weeks ago with a women who had lived through the Great Leap Forward in China describing her feelings for Mao at the time. She really did think of him as infalable, to the point of coming up with complicated and unlikely scenarios to explain the failings of the Chinese state.
How about “drink plenty of fluids”?
Nope. You could be suffering from problems with the upper gastro area, where liquids by mouth are contraindicated.
This one I can go with.
Orgasms are fun.
I was thinking that I had no idea to answer the OP and then I stumbled on this post. I immediately took a poll of my 12 & 14 year old. Without hesitation they said: “Bugs Bunny.” (without prompting)
I’m inclined to go with Little Nemo on this one.
An abomination before God.

Another couple of suggestions - aphorisms rather than principles, but still.
“Hear all, see all, say nowt, and if tha ever does owt for nowt, do it for thissen.”
“Keep your mouth shut and your bowels open.”
“John Edward is the Biggest Douche in the Universe.”
I think we can all agree that no, there is not something we can all agree on.
Go ahead, try to disagree with that!
No they can’t.
Again, I imagine that the folks at Disney would hold, even before the Owl God, that MM is the better cartoon character.
I’ve also heard people (usually of the elder generation) express a dislike for the rabbit and a preference for the mouse because they feel Loony Toons, with its emphesis on the anvil smashing and TNT explosioning of its villians to be too sadistic.
