Common, ordinary word.

[SANDMAN5]

Friend of mine tried to convince me that there's a common, everyday word
in the English language that has the letter "u" in it three times. He wouldn't
give me a hint except it's NOT a name or scientific word. Just a 'plain old word'
that we've all used dozens of times. I racked my brain trying to figure it out,
even had an extra cup of coffee trying to get my 'thinker' working better.
Never did find out what it is. I think he's lying to me. I don't think that word
even exists. If it does exist, it sure must be unusual!

[ricoman]

It really must be unusual.
I can't think of it either.

[..]

My brain is working so hard to think of what it could be it feels quite tumultuous.

[bassman]

For some reason this is unusually difficult to figure out

[Kaiser]

It really must be unusual.
I can't think of it either.

Unusual, indeed.  Hope you figure it out!

[Serk]

While we're at it, how 'bout this one:

What is unusual or odd about this particular grouping of words?

[hubcapsc]

I before E, except after C. Is that a sufficiently weird enough rule for you?

[Disco]

What is unusual or odd about this particular grouping of words?

No "e". 

[Serk]

No "e". 

We have a winner! Most common letter in usage, and that sentence has none of them...

OK, here's another.

What single word has three sets of double letters (I believe there is only one)?  (ie: aabbcc)

[bogator]

Mississippi            I think??????

Bookkeeping be the word you had in mind? (Or Bookkeeper, or bookkeepers, or some other iteration of the same?)

[Disco]

OK, how 'bout a 6-letter word with 3 "y"s in it.  

[SANDMAN5]

My brain is working so hard to think of what it could be it feels quite tumultuous.

Don't think that would be it....I've only used it a couple dozen times.

OK, seven-letter word with all five vowels.

Bookkeeper is correct.  (Mississippi is not)

[Brad]

OK, seven-letter word with all five vowels.

sequoia, eulogia, miaoued, adoulie, eucosia, eunomia, eutopia, moineau, and douleia.

How about "possessionlessness" and extra one for good measure

[hubcapsc]

sequoia, eulogia, miaoued, adoulie, eucosia, eunomia, eutopia, moineau, and douleia.

adoulie is my favorite kind of sausage, I get all eunomic just thinking about it, douleia?

OK, seven-letter word with all five vowels.

I was taught in school that the vowels are A, E, I, O, U, and sometimes Y and W.

[SANDMAN5]

I was taught in school that the vowels are A, E, I, O, U, and sometimes Y and W.

Me too also....but WHEN is W a vowel?!?! ???

[Disco]

6-letter word with no vowels.

Note that I didn't say no "sometimes" vowels.

SUBSTITUTE VOWELS 
It is finally time to introduce the substitute vowels. We simply tell the children that Y and W can sometimes be vowels.

When is W a vowel?

When w follows o, and the o says it's name, the w is acting like a vowel (follows double vowel rule above).

In these words: cow, town, brown, etc., w is a consonant.

In these words: tow, low, bowl, etc., w is a vowel. Notice the o is long and the w is silent.

Like the oo words, we don't fuss over the difference, but just practice some words and let the child get used to them.

When is Y a vowel?

Y acts as a vowel when it comes at the end of a word. It follows the double vowel rule in words that end with the following:

Words ending in -ay have the long a sound, such as pay, May, play, etc.

Take the phrase 'Dick and Jane'.  There is a space between Dick and and, and and and Jane.

Two English words that are both homonyms and antonyms.

Tell your friend that the word gullible is not in the dictionary.

nope, y is a sometimes a vowel so it cannot be that one. It is one of my favorite vowels.

Nookkeepers would also work.
1. Nookkeeper is a person that keeps your nooks clean
2. Nookkeeper is a person that stores Nooks as opposed to one that stores Kindles.

[Disco]

ys that?   

[Big IV]

It is one of my favorite vowels.

ys that?  

I'm a big fan of letters that are also words, especially when they are spelled differently. Sound combination are fun.
Eye
Aye
why
oh
you

Those are great vowel sounds.
