I don’t have a cite on the stat, so ignore it if you like.
This is probably too easy for the Teeming Millions, but…
When asked this riddle, 80% of kindergarten kids got the answer, compared to 17% of Stanford University seniors.
What is greater than God, More evil than the devil, The poor have it, The rich need it, And if you eat it, you’ll die?
Please throw out your fave riddles too, I’m always looking for new ones.
Is this in the right place, or should it have gone in MPSIMS?
nothing.
here’s an oldie, but a goodie… what common english word contains all the vowels (including ‘y’) in order (non-consecutively, of course) from left to right. Each vowel appears only once?
And… what’s the shortest English word that contains the letters “a,b,c,d,e,f”?
“what common english word contains all the vowels (including ‘y’) in order (non-consecutively, of course) from left to right. Each vowel appears only once?”
Well, “abstemiously” fills the bill, but I don’t know how common it is. It means sparingly or modestly.
Consecutively I can’t be serious
“facetiously” also works, but I haven’t used it in conversation lately, either.
facetiously
befaced, if yer fond a highfalutin’ words…
What word has three sets of double letters?
Bookkeeper
Bookkeeper. I got that one from encyclopedia brown.
What we caught we threw away, what we didn’t catch, we kept.
What is the riddle talking about?
Fleas.
Webster’s second has “subbookkeeper”, unhyphenated. Webster’s third doesn’t. 
Incidentally, I did a search on Google to check whether it was a real word or not… and the last page it found (it only found sixteen) seems very weird…
What answer should not be given to this question?
Lice on the body. Ick.
I have no sword, I have no spear
Yet rule a horde that many many fear.
My soliders fight with wicked sting;
I rule with might, yet am no king.
What am I?
My guess is a queen bee.
The more you take the more you leave behind. What am I talking about?
The answer to Verrain’s riddle is A Queen Bee.
Since I don’t have one right off the top of my head, someone else gets my turn 
A queen bee!
This thing devours all birds, beasts, trees, flowers
Gnaws iron, bites steel,
Grinds hard stones to meal,
Slays kings, ruins towns,
And beats high mountains down.
-JRR Tolkien
Time of course.
And Baraqiyal, is it dirt from a hole?
Complete the sequence: O,T,T,F,F,S,S,E…
It is something you all know well.
A hole.
What’s at the end of everything?
To answer Tot’s riddle, it’s the letter “g”
On my way to St. Ives
I met a man with 7 wives
Each wife had 7 sacks
Each sack had 7 cats
Each cat had 7 kittens
Kittens, Cats, Sacks, Wives
How many were going to St. Ives?
One. YOu were going to St Ives. THey all were going the other way. I have a riddle above but here is another.
You break it even to name it.
No, not a hole or dirt from a hole but good guess. I’ll give it a few more hours before I post the answer.
This one is the first letters of the numbers starting with:
One, Two, Three, etc.
Silence, of course.
Still puzzling over Baraqiyal’s last one…
Hmmm…all the ones I can think of are from The Hobbit too, Rasa. Or the Riddle of the Sphinx. Call me a sucker for the classics. Or unimaginative, I suppose.
Maybe I’ll think of one later.
