Rainbow Dash: hnnnnnnnng! (white thing comes out as a circle then turns into a triangle as electricity comes out, she stretches as the triangle has some colors at the tip. White circle comes out)  
BOOM!  
Rainbow Dash makes the white circle again as the triangle and white circle forms and does a Double Rainboom  
Rainbow Dash explodes  
Princess Celestia: Congratulations, Mane 6. Due to Rainbow dash, (rainbow dash gasps) I will change all of your roles.  
Rarity: My perfect horn! I’m an earth pony! Oh sweetie belle…  
Twilight sparkle: MY HORN! not a pegasus…………  
(Rainbow dash is an alicorn)  
(meanwhile)  
Twilight: Hnnnng…………………….. (does a sonic starboom)

I’m pretty sure this was the exact moment I became a Brony.

Removing artist tag; uploading a screencap doesn’t make one an artist, any more than copying Hamlet’s soliloquy makes one a playwright.
