Twilight Sparkle: Oh, I am excited. But, to be honest, I'm a little nervous, too.
Pinkie Pie: You're 'nervicited'! It's like you wanna jump up and down and yell "YAY ME!!" But you also wanna curl up in a teeny-tiny ball and hide at the same time! We've all been there!
Fluttershy: I'm there almost every day.
Nerd: I like totally changed the rendering mode to openGL!
Normal kid: Uh what?
Nerd: *Insert weird explanation here"
Normal kid: huh?
Nerd: I know its complicated
Normal kid: It's not complicated, it's NERDYCATED!
