Pinkie Pie: It’s Silly Hat Day! (calls friends on her banana phone) AYYY!  
5: AYYY!  
Rarity: I sent you all something darlings.  
Fluttershy: (giggles) Really funny.  
Starlight Glimmer: What’s Silly Hat Day?  
Rainbow Dash: It’s a holiday when you have a party with your friends!  
Pinkie Pie: And they where silly hats!  
Applejack: And dance like CRAZY!  
Pinkie Pie: We should have it at Sugarcube Corner. I’m wearing my fez!  
Rarity: I’m going to wear my tiara.  
Twilight Sparkle: Rainbow Dash and I will be wearing our party hats.  
Rainbow Dash: Yeah! That’s right!  
Fluttershy: I’m wearing my flower hat.  
Applejack: I’m gonna wear my red and white apple pattern hat.  
Starlight Glimmer: Oh! What hat am I supposed to wear?!?! (calls Trixie)  
Trixie: Hello?  
Starlight Glimmer: Trixie, I’m having trouble figuring out what hat to wear! Do you have your magic hat on?  
Trixie: Yes. Yes I do. But it has bunny ears on it.  
Starlight Glimmer: (snickers) That IS silly. Bye Trixie.  
Starlight Glimmer: (thinking) Should I wear a bow? No. Too fancy. A Sombrero? Nah. Too spicy. Wait! What about a jester’s hat? Perfect! (Puts on jester’s hat)  
Starlight Glimmer: It’s party time. (trots over to Sugarcube Corner)  
(door knocks)  
Pinkie Pie: (squeals) STARLIGHT’S HERE!!!!!  
Starlight Glimmer: How do I look ponies?  
Rainbow Dash: Very silly!  
Trixie: Super cool hat!  
Starlight Glimmer: Thanks.

@Prof.NightJack  
No! I’m sure the whole mane 6 does have silly hats on.

Ahh, good times of Stick Figures on Crack!

@Prof.NightJack  
B-but, fezes are cool!

Looks at tags  
Sees “Don Hertzfeldt”  
Laughs at the juxtaposition of cheefrul multicoloured ponies interacting with a world of surreal/maddening abstract thought and depressing monochrome landscapes.  
What was I talking about?

Rainbow Dash….I’m sorry but
 

@Kerion  
Maybe, but even then it’s not silly.

@Prof.NightJack  
Some people consider the fez to be a funny hat.

@JC the Hedgehog  
Sounds par for cable TV.

cuts to Twilight and friends hitting Rainbow with bats

I approve heartily of Silly Hat Day.

Only two of them have silly hats.  
THROW THE OTHER FOUR BUMS OUT!  
And I’m ashamed of you Pinkie, not to have a silly hat.
