What is the common theme?
_ _ _ _ == _ _ _ _ _ _
CHRIS TUCKER
ROSIE PEREZ
JAY LENO
BERNADETTE PETERS
BETTY BOOP
FRANKIE VALLI
MICKEY MOUSE
========================
I know I’ll hate myself for not being able to figure it out for myself.
Nevertheless, I gots to know!
Celebrities?
None of them have ever been in my kitchen.
At least that much, for sure.
But the 4-letter + 6-letter answer has me stumped.
I can easily imagine there’s some way to phrase “face peculiarities” but not one that has fit yet.
What’s hanging me up the most is trying to find a phrase that incorporates:
CHRIS TUCKER – prominent to bulging eyes
ROSIE PEREZ – prominent cheek dimples
JAY LENO – prominent to exaggerated chin
BERNADETTE PETERS – tiny mouth (bow-shaped lips)
BETTY BOOP – funny-shaped head (heart-shaped even) and Bernadette Peters mouth
FRANKIE VALLI – traingular shaped head
MICKEY MOUSE – ears, weird head shape
None of them have a grant of nobility, and they’re therefore all commoners? OK, that’s pretty weak.
Maybe each of them has had a movie with the word “common” in the title? Unlikely…
I don’t think it can be funny-looking faces, because that doesn’t work in “common”. And besides, you can find a facial peculiarity in just about anyone.
I got it.
Hint: None of those traits are relevant.
“Common Knowledge” is the name of the daily (weekdays) puzzle where you work a Hangman-styled puzzle for the clue words and then try to find what they have in common. Today’s “common” theme is a 4-letter/6-letter phrase.
Since two of the clues are cartoon characters I ruled out human connections beyond appearance features. That could be a wrong tack. But I have yet to get the answer that solves the puzzle. So I posted it here for help.
I’m not meaning to dispute your “And besides, you can find a facial peculiarity in just about anyone” statement, and it could be something else I haven’t thought of that they share. I just went into the facial features as something that appears noteworthy in several of them (Frankie Valli the least).
I assume it’s a word puzzle, and has something to do with the number of letters/consonants/vowels/whatever in the words.
No big surprise! Can you give another hint?
High pitched voice.
ETA: To fit your format… high voices.
The same venereal disease?
You Da Man! That’s it!
It took a while…but answer is…
HIGH VOICES
Oh, OK, I hadn’t checked the link, and was assuming that “common knowledge” was a crossword puzzle theme.
i thought it was “Walt Disney”.
Answer is High Voices
I don’t think that RosiePerez has a high voice. It’s certainly distinctive, but not high for an adult female.
And I was wrong about that… guess I’ve seen too many puzzles where they try to fake you out by giving you a list of members of some broad category but what they’re really looking for is related to the words’ structures, or puns related to the word, or whatever and the category is just a distraction.
All I can say is that I think of dimples and some crazy dance moves (in Do the Right Thing (1989)) before I think of her voice! 
The “Common Knowledge” format is rarely outright tricky like that, but it’s not out of the question. I rarely have to go further than my wife for help, but this one was too tough for her, too.
Thanks to all for contributing. Think of this thread if you run into trouble on one of your own.
It’s often the case that I can get the “common theme” answer without all the clue words. But once I have that I go back until I solve all the clue words, too. Today’s is an example of that!
