Well, I'd been watching Trailer Park Boys, and ... Rule 85 dictates that this needed to happen. Not 100% happy with it, but I have a hard time putting multiple ponies in one image.

Derpy as Bubbles was the concept that spawned this. Mainly he has funny looking eyes ... and his name is BUBBLES, which is Derpy's cutie mark. That combined with my husband commenting that Bubbles is, ironically, one of the most intelligent characters on the show, which also happens to be my husband's head-canon for Derpy.

Rainbow Dash as Ricky--I saw the Season 5 episode "Tanks for the Memories" and thought, "Okay, Rainbow Dash is Ricky!". Her actions in that show just struck me as something Ricky would do. And, yes, she is smoking a joint XD

As for Applejack as Julian ... basically, since they're pretty much rednecks, I figured one of them had to be Applejack, so she got Julian XD Also, I figured the drink he's always carrying around could be (hard) apple cider in her case.
