I have a feeling that today's Brain Game may be tough. You'll prove me wrong, won't you? Anyway, here's a quick list of five words selected just for you:

INHARMONIOUS
URINALYSIS
MARSHMALLOWS
JOURNALISM
SYNONYMOUSLY

Now, one thing may immediately jump out at you about the words in that list: None of them contain the letter E, and that gets you on the right track. But check a little closer, and you may discover something even more specific and unusual about these five words when compared to most others that are anywhere near as long. (And yes, the title of today's Brain Game is a subtle, if obscure, hint.) What do these words have in common? 

Here's the SOLUTION.

SOLUTION:

None of the letters in the words even rhyme with the letter E. You'll find not a single B or C or D or E or G or P or T or V or Z in those words.
