It's me, Nikki Limo.

You might know me from my YouTube channel,

where I do comedy sketches and blogs.

But right now, I'm here, filling in for Jacob.

Every day, YouTube Nation brings you the best videos around.

Today we have Disney a capella, [MUSIC - JON COZART,

"AFTER EVER AFTER"] a unicorn slayer,

and Hannah Hart's VidCon tips.

HANNAH HART: Don't forget to spray tan.

MALE SPEAKER 1: I'm having fun already.

NIKKI LIMO: Last March a film student

at the University of Texas in Austin

racked up over 30 million views by singing

the story of what happens to Disney's princesses after ever

after.

Well, guess what?

Jon Cozart's back.

He just released this sequel, and it already

has over a million views since Tuesday.

[MUSIC - JON COZART, "PAINT"]

Each is filmed in a single take, which is nuts,

considering how spot-on the harmonies are.

And this guy is only 22 years old.

Princess Leia better watch her back.

MILES: Guys, I'm starting a new diet.

I'm moving onto a protein that's nutrient-rich, environmentally

friendly, and more abundant than most other foods on the earth.

I'm talking about bugs.

This compelling piece on the merits of a bug-based diet

was just uploaded by AsapSCIENCE.

And they make some pretty interesting points.

MALE SPEAKER 2: It's not like our mouths have never

tasted insects before.

For every 100 grams of spinach, 50 small insects

like aphids, thrips, and mites are permitted.

Peanut butter is allowed to contain

roughly 30 insect fragments.

And even the hops used to make your favorite beer

can contain 258 bits per 100 grams.

If you think you're switching to a creepy-crawler diet

and you need some recipes, head over

to AsapTHOUGHT 'cause they've got some great tips on how

to cook these bugs.

Delicious.

NIKKI LIMO: Summer's here, but if you weren't cool enough

to be invited to a pool party, don't worry.

Rhett and Link's wearable pool system is here to the rescue.

The guys just released this.

And while the ideas are great in theory,

the application of them is--

RHETT: Pool boots, also known as a "poolts."

LINK: The pool shirt.

RHETT: I feel great.

My butt feels really good.

Pool pants, or "plants."

LINK: Pool head.

NIKKI LIMO: For more summer ideas,

be sure to tune in tomorrow for a special beach-style episode.

LIZZIE: There are over 12 million skateboarders

in this country, but less than a quarter of those are female.

Three six-year-old girls are about to change all that.

God bless America.

"The New York Times" just posted this short doc

on the Pink Helmet Posse of Encinitas California.

It also screened at the Tribeca Film Festival.

MALE SPEAKER 3: What I'm learning

is there's no limits to what they can do.

FEMALE SPEAKER 1: I think it's pretty cool

that six-year-old little girls are

dropping in bowls and stuff.

FEMALE SPEAKER 2: I'd like to see the Pink Helmet

Posse everywhere, and little girls everywhere

are just having fun skateboarding.

I think that'd be awesome.

LIZZIE: If you think you can handle

more of this impressive skate action,

they have their own Instagram account and their own website

and shop.

That was an adorable face-plant.

NIKKI LIMO: I love VidCon.

It is like spring break but with less wet t-shirt contests

and more socially awkward YouTubers.

It's happening right now.

But if you're a first-timer, you might

want to listen closely to Hannah Hart.

HANNAH HART: Tip number one.

Have a great time.

Tip number two.

Have a great time.

Tip number next.

Stay hydrated.

You guys are going to get really thirsty from all the screaming

and the chasing that's going on.

And now I'd like to stress the most important element

of VidCon.

Deodorant.

Deodorant.

Jacob Is there right now, and tomorrow we're

posting a special VidCon episode featuring

some of your favorite YouTube creators.

Carly also put together a playlist of VidCon moments

to get you ready for the big weekend.

I will see you there.

If you see me, you better say hi or I will feel lonely.

EARNEST: Here's a little secret.

I am generally not fond of baby videos.

But I'll make an exception for this one,

because it is just a piece of YouTube brilliance.

February 14, 2011, twin babies just talking to each other.

It was one of those videos that the entire internet just

stopped to watch. [BABIES BABBLING]

The video spawned a number of parodies,

including one from CollegeHumor.

And Patton Oswald even got in a diaper to recreate this video.

This video just hit 100 million views.

Very few videos ever reach that mark.

And these two little kids did it.

NIKKI LIMO: You got a favorite video from the past?

Leave it in the Comments with the hashtag "Throwback

Thursday."

Every Saturday this show's devoted to one subject.

And this week it's awesome POV videos like this one.

[INAUDIBLE] Jacob's back tomorrow

with the VidCon special.

But until then-- play us out, Lydia Ainsworth
