 What kind of a pie is that? It's just numbers! Well...a never-ending supply of pie sounds great!

Twilight, spoiler alert, but at the end 'pie' killed 'pi' !

"If Pinkie and her family know this by heart, I must do as well! I MUST!"
-Hey Twilight!
"Hi Pinkie."
-Did you know that the 2,455th digit number is 6?
"... "
She closed the book, let it drop on the ground and left.
"UGH!'
-Huh? Hey! Where are you going?
"SCREW THAT! I HAVE BETTER THINGS TO DO!"

BTW, I checked. www.angio.net/pi/digits.html

That look on her face is priceless.

so it's an infinite book? wow, it must be very heavy!

I love the shading and colors

Her face looks like shes seen some shit, though that's probably because shes trying to find the end of pi. xD

Dunno why, but I can see Pinkie spoiling the ending.

I'll give her a book about e. lol

Well, at least she's having some pie.
