D
Hey, Reggie, guess what? You were in my dream last night.
C
Yeah?
D
Last night I dreamed we were water skiing down a river made of salsa verde and we were being chased by robot chinchillas. What do you think it means? What? What do you mean I need to stop eating cheese before bed. Oh, and I suppose next you'll tell me I need to stop eating cheese in bed. Reggie, it's perfectly fine to eat cheese in bed. You know the old saying, early to bed to eat all the cheese. This rhyme brought to you by the Dairy Board of Trustees.
A
Uh, Dennis.
D
Oh, hi, Guy Raz. What can I do for you? Do you need some cheese?
A
Um, could we start the show now?
D
Oh, right.
C
Ahem. You there.
D
Stop the watches. And you tumble the weeds. And Reggie, slide the whistles. We're on in three, two, one.
A
And now for everyone's favorite game show, it's two once and a Whoa.
C
With your hosts, Mindy and guy R. 2 what's 2? What? 2 what's 2? What's 2? W 2 what's and a wow.
B
Hello, and welcome to 2 what's and a wow.
C
2 what's and wow.
A
The scientific game show that separates the wows from the what's and the category or the theme for today is Sleep. Mindy, why don't you refresh our contestants on how the Game works.
B
You know it. Wowzers. In each of our three rounds today, Guy Raz and I will present you with three scientific statements about sleep. But this is a big but. Only one of those statements will be a true wow. The other two, just a couple of made up.
C
What?
A
In each round, if you guess correctly, congratulations, you win a point.
B
But if you guess incorrectly, you must stop, drop and do a ridonkulous physical challenge.
C
Shh.
A
Okay, everyone ready to start the game?
B
Great. Let's get to it.
A
All right, round one. Which of the following statements is a true scientific wow? Is it A, humans sleep best during a full moon?
B
Or is it B, the average person falls asleep in about 7 minutes?
A
Or is it C? We go through 6 different stages of sleep every night.
B
And when you think you have the correct answer, scream, hey, where are my fuzzy slippers?
C
Psst.
B
Reggie, cue the thinking.
A
And time is up. Let's now reveal the winning wow.
B
And to do just that, it's seven from Alaska. Seven from Alaska. Tell us, what's the wow?
E
Hi, Mindy and Guy Raz. My name is Seven and my wow in the world is that the average person falls asleep in seven minutes.
B
Winner. Winner clocks for dinner.
A
Thank you. Seven contestants. If you guess the answer B that the average person falls asleep in about seven minutes, well, congratulations. You found the winning wow.
B
When it's time for bed, you don't fall asleep this time. Second, your head hits the pillow. It takes about seven minutes for your brain and body to transition from being awake to conking out.
A
The amount of time it takes you to fall asleep is called sleep latency. It's believed to be a creative sweet spot or a moment when your brain might experience a spark of creativity.
B
Now, if you did not get that answer correct, you must stop, drop and sleepwalk around the room.
A
Okay, round two. Which of the following statements is a true scientific wow? Is it A, the average dream lasts 20 minutes?
B
Or is it B? About a third of humans dream in black and white.
A
Or is it C? We mostly dream about people we have never met.
B
When you think you have the correct answer, scream, I need a midnight snack. Hey, Reg. Thinking music, please.
A
And time is up. Joining us by phone, it's Jack from Colorado. Jack, please reveal the winning wow. Hello.
E
My wow in the world today is that the average dream lasts about 20 minutes.
C
Wow.
E
Isn't that fascinating?
C
Winner, winner.
B
Dreamsicles for dinner.
A
That's right, Jack. Wowzers. If you guessed A that the average dream lasts 20 minutes, you found the winning wow. Congratulations.
B
When we sleep, we go through cycles which last about 90 minutes each. Our dreams happen in the last part of the cycle and the average dream is about 20 minutes long. But some can last up to a whole hour.
A
The part of the sleep cycle when dreams happen is known as rapid eye movement or REM sleep. It's called that because our eyes move around under our eyelids.
B
Now, if you did not get that answer correct, you must stop, drop and act out that dream where you accidentally wore your pajamas to school.
A
Okay, round three. Which of the following statements is a true scientific wow? Is it A, some birds sleep while flying?
B
Or is it B, Large dogs have fewer dreams than small dogs.
A
Or is it C, Sharks never sleep.
B

C
Two what's and a wow.
B
The scientific game show that separates the wows. From the what's.
A
Now, before the break, we left you with a dangling question for round three.
B
And that question was which of the following statements is is a true scientific wow? Is it A, some birds sleep while flying?
A
Or was it B, large dogs have shorter dreams than small dogs.
B
Or is it C, sharks never sleep.
A
And joining us by phone to reveal the answer, it's Riley from Georgia. Riley, tell us the wow.
E
Hi, my name is Riley. My wow is that Some birds sleep while flying.
B
Winner, winner, night owls for dinner.
A
Thank you, Riley. Contestants, if you guessed the answer A, that some birds sleep while flying, well, congratulations, you found the winning wow.
B
Sea birds, called frigate birds travel long distances over the ocean and can stay in the air for up to two months. And because they can't swim, they can't land in the water to take a snooze.
A
So Instead they take 10 second naps while flying, giving them about 45 minutes of sleep per day. And they'll often sleep with one side of their brain still awake.
B
Now, if you did not get that answer correct, you must stop, drop and do a barrel roll. What was that that sound can mean only one thing.
A
Mercury is in retrograde.
C
Nope.
B
It's time for today's Bonkerballs bonus round. And the question for this round is, what came first first? The pigeon or the egg?
A
Don't you mean the chicken or the egg?
B
Yeah, that's what I said.
A
Okay, well, congratulations to all of our winning wowzers. Mindy, what's today's prize?
B
Guy Raz Today's winning wowzers will all receive their very own gumball getter.

Gumball getter?
B

A

B
Let so you open your wallet and you pull out one of these shiny little beauties and you shove it into the machine and you get a gumball.

C

A

B
But before we go, we have a a little scientific challenge for you. We call it Operation Dream diary.
A
We forget 90% of our dreams within the first 20 minutes of waking up. But when you write your dreams down, you can have a record of them forever.
B
For this, we challenge you to put a piece of paper, a pencil, and some crayons next to your bed before going to sleep. Then, when you wake up in the morning, write or draw the dream you just had.
A
Remember to record your dream the moment you wake up so you can capture as much as possible.
B
